VoL XI JANDARY-NARCH, 1923 Nos. 1-3 




In revising this family, with Mr. Neumoegen, over a quarter 
of a century ago, I placed Platoeceticus Packard as having 
vein 6 absent in the hind wing. Further material shows that 
this condition is exceptional, the majority of specimens having 
vein 6 present on both wings. Vein 6, when consistently 
absent, is absent on both wings. This reduces the number of 
our genera by one; furthermore, there are older names given 
to European species for both of the remaining genera in this 

In the other group, in which vein 1* of fore wing is obsolete 
between vein I** and the inner margin, was contained Chalia 
rileyt Heylaerts. This species cannot rest in Chalia, which is 
unrepresented with us, but may find place in Apterona Milli^re. 

Prochalia pygmaea Barnes & McDunnough, about which a 
warm controversy raged at the time of its description, proves 
to be distinct from the more northerly distributed form which 
resembles it, as the latter has lost vein 9 in the fore wings. 
A new name is suggested for this.

Fore wing with 18 veins; hind wing with 8 veins (vein 7 of fore 
wing free or staBced with 8-9; vein 6 of hind wing rarely absent), 
Payche Schrank (180S), Platoeceticus Packard (1869), Manatha 
Moore (1877).

Pachytelia confederata Grote & Robinson. 

Originally described from Texas, ranging as far northward 
as Maryland, The peculiar cases, longitudinally thatched with 
narrow grass-stems, are well known. No material from Texas 
is before me, all of the specimens originally collected by Bel- 
frage in Clifton, Bosque County, being carbonaria, so that 
perhaps this name is misapplied. 

Pachytelia carbonaria Packard. 

Larger than confederata, and known only from Texas at 
present. The larval case is unknown. 

Pachytelia traceyi Jones. 

The robust body and short wings easily indicate this species. 
The larval cases are covered with broad flat grass-blades. 

Pachytelia celibata Jones. 

This and the following were very recently characterized by 
Mr. Jones under Psyche (Eurycyttarus), In both of them, 
vein 8 of hind wings joins vein 7 by a broad anastomosis in- 
stead of a bar, as in the other species of the genus. 

Pachjrtelia cacocnemos Jones. 

Superficially like traceyi, but differing in structural details. 
Pach 3 rtelia fragmentella Hy. Edwards. 

Described from the larval case, Strawberry Valley, Siskiyou 



County » California, covered with pieces of (pine) leaves and 
bark. I'he conifcrclla of this same author, found in Grass 
Valley, California, ''on palings and trunks of pines/’ is pre- 
sumably the same. The adult is undoubtedly the one described 
by Butler as Hyaloscotes fumosa, the type being from Mount 
Shasta, and four males from Siskiyou County, California, as 
1 was informed by Sir George Hampson many years ago. I 
have a larval case from Easton, Washington, which is covered 
with fragments of spruce leaves, but may nevertheless be this 
species. No adults are before me. 

Pachytelia pithopocra, new species. 

W ings thinly scaled, gra), without markings. Veins 1* and 

anastomosing shortly l)efore vein 1** branches to the inner 
margin. Expanse, 20 mm. 

The hvpopygium (pi. 1, fig. 1) has the plate of the ninth 
.segment (juadrate, with a central rod reaching two-thirds of 
the internode. Internodes 8-i> and 7-8 bare. Plate of the 
eighth segment with two rather long, widely separated rods. 
(']as|)ers simple, the inner division pointed and without teeth 
(pi. I, fig. o). Basal ventral abdominal plate (pi. I, fig. 2) 
with long basal horns, followed by a small narrow plate before 
the plate of the third segment, which is indented on the anterior 

Ty{)C, male, U. S. Nat. Mus. ; Collins, Idaho, July 27, 1898 
(C. V. Piper). 

Formerly identified as Psyche fragmcntella, but in the adult 
of that {Hyaloscotes fumosa) vein F does not anastomose 
with 1**, but is joined to it by a bar, as indicated by a sketch 
made for me by Sir Oorge Hampson. 

The case of pithopocra is covered with rather flat grass- 
blades, laid on lengthwise. 

Two other cases are before me, Blue Mountains, Washing- 
ton, Jtily 15, 189() (C. V. Piper), which are covered with grass- 
blades and pieces of leaves (perhaps Eriogonum), Without 
adults, nothing certain can be said of them. 



Psyche gloveri Packard. 

1 formerly referred Manatha cdwardsii Heylaerts to this 
species (in 1893) ; but perhaps the name refers to carbonaria. 
Barnes and Benjamin have recently described Mcmatha jonesi, 
in which the antennae are said to be more shortly pectinated. 
I cannot perceive any tangible difference in this respect in my 
material. I have no specimens from San Benito, Texas, which 
they make the type locality ; but I have specimens from Browns- 
ville, I'exas, which is in the same region. I am inclined to 
surmise that jonesi may be the same as gloveri or nigrita, 
according to what the larv^al cases may be found to be. 

The larval case of gloveri is characteristic, Ijeing covered 
with very small fragments of bark and leaves. 

Psyche nigrita P>arnes & McDunnough. 

There is no tangible difference in the adults ; but the larval 
cases are covered with long narrow grass-blades, densely 

Oedonia cxigua Jly. Edwards. 

I'his species has not reairred. It may not l)elong to this 

Prochalia pygmaea i>arnes Sz McDunnough. 

Apparently similar to the following, except in venation. 
Described from Everglade, Florida, the larval sacks on the 
trunks of orange trees, which were covered with lichens. 

Zamopsyche commentella, new genus and species. 

Fore wing with vein 1 without a branch; veins separately 
from the cell, 7-8 shortly stalked, 9 absent, 10 and 11 from the 
cell. Hind wing with 'Z and 3 from the cell, 4 5 connate at 
origin, 0 and 7 from the cell, 8 jointed by a weak oblique bar 
toward the middle of the cell. Wings elongate and rather 
narrow; lx>dy slender. Subtranslucent blackish brown with 
slight bronzy tint. Expanse, 13 mm. 

The hypopygium (pi. I, fig. 4) has the plate of the ninth 
segment rounded, with a long rod which crosses the internode 


and projects into the eighth segment. Intemodes clothed with 
fine vestiture. Plate of the eighth segment with two distant 
and rather short rods. Clasper with the inner portion toothed 
(pi. J, fig. 5). 

The larval vsack is cylindrical, mixed with excrement and a 
few fragments of bark adhering to the outside. 

Types, two males, U. S. Nat. Mus. ; Vienna, Virginia, Sep- 
tember 11)11, larval case on apple-bark (R. A. Cushman) ; 
Whitaker, South Carolina, “on elm'* (E. S. G. Titus). 

Aptcrona rileyi Heylaerts. 

1 have a si>ecimen which api>ears to agree entirely with the 
original description, Kearney, Virginia, collected on Quercus 
marylandica (A. Busck), the adult issued June 18, 1914 (C. 
Heinrich). The wings are of the usual shape, broadly rounded. 

The hypopygium (pi. 1. fig. has the plate of the ninth 
segment broad, distinct onh anteriorly, with rounded margins 
and a very long central rod running back almost to the inter- 
node 7-8, Plate of the eighth segment weak, the rods long 
and very slender. Inner division of the clasper strongly toothed. 
1'he internodes api)ear to be bare; but as the specimen was 
denuded before mounting, this cannot be positively stated. 

Apteiona fragilis Karnes & McDunnough. 

Described from .Arizona, and not known to me in nature.

Cucullia phila Barnes & McDunnough, Check List Lcp. Bor. Am , 
55 , 1917 . 

Strecker described from Florida, Smith from Pennsylvania. 
The mistaken reference to Copicucullia has prevented the recog- 
nition of the species and caused the redescription by Smith. 
Specimens are in the National Museum from Tryon, North 
Carolina, August 8, 1904 (W. F. Fiske), Raleigh, North Caro- 
lina, August, 1911 (C. S. Brimley), Clarksville, Tennessee, 
August 6, 1922 (S. E. Crumb), Cadet, Missouri, August 11, 
1890 (J. G, Barlow), and Glencarlyn, Virginia (H. S. Barber), 
the latter being a larva, which matured on October 10, 1922. 

The larvae feed on wild aster, and are conspicuous late in 
the fall eating the flowers and seed-pods. The species is single- 
brooded, larvae maturing in late September and early October, 
not appearing as moths until August of the following year. 

Larvae sent to the Bureau of Entomology by J. G. Barlow 
in the fall of 1889 were briefly described by the late Theodore 
Pergande as follows: 

“Length V/i inches. Head and body shining. Color black, 
orange and lemon yellow and white. Head black, with a triangle 
in front, large spot on cheek, and antennae except apical joint, 
white. Body with a wide dorsal orange stripe lighter (lemon 
yellow) between segments, extending from the head to anus, 
but narrowly interrupted with black on shield of first segment ; 
then a wide black stripe, reaching to and including the stigmata. 
The lower half of this stripe is interrupted by transverse lemon 
yellow spots, three or four to each segment. Then follows a 
substigmatal stn])e uniformly orange, and much darker than 
the dorsal stri])e; \ enter and feet white with black markings.*' 

The larva collected by Mr. Barl^er last fall was noted as 
follows : 

Head rounded, the vertex beneath joint 2, pale green on 
the sides, with difFuvSe black bars ; face black, a broad, pale 
green inverted V-mark over clypeus; epiwStoma pale green. 
Antennae pale. Skin dull, wrinkled-shagreened. A broad 
bright orange-red dor.sal band, constricted on joint 2 and on 


the hump on joint 12; subdorsal area black, running down 
broadly to the spiracles, and narrowly anteriorly and posteriorly 
on the segments, between these black bars, pale green. A broad 
bright orange-red substigmatal line, slightly waved on the seg- 
ments, without border, but with black on the tubercles and 
bars in the incisures anteriorly and posteriorly. Venter and feet 
pale pea -green. The pale green lateral area runs up to the 
dorsal red line on joint 2 (anteriorly and posteriorly), 12, 13 
and 14. Tul)ercles invisible. 


{Diptera, CuHcidae) 

Mcgarhinus moengocnsis, new species. 

Female: Protoscis long, slender, pointed, curved. Palpi 
long and stout, about two-thirds of the proboscis. Terminal 
segment minute ; vestiture metallic blue and purple, the apices 
of the segments light violet, golden scales beneath and on 
sides, except on basal section of the palpi which is blue and 
purple all round. Occiput covered with flat irregular light 
green and blue iridescent .scales, ocular margins, cheeks and 
head beneath silver scaled. 

Prothoracic lobes with flat vsilvery blue scales and a few 
setae. Mesonotum clothed with small brown scales on disk, 
the lateral margins, a median slri|)e in front and the complete 
IKi.sterior part with metallic green and blue scales. A patch of 
blue scales in front of the wings. Scutellum with greenish 
silver scales, Postnotum brown, nude. Pleurae and coxae 
brown, densely covered with silvery scales. 

Abdomen subcylindrical, broadest at middle ; dorsal vestiture 
Imsally olive green, fifth segment with golden blue scales, fol- 
lowing segments deep blue with golden scales apically; venter 
with golden scales and a narrow blue longitudinal median 
stripe, widest on fourth and fifth segment, disappearing on 
eighth segment. 



Wings narrow with smoky tinge, cross veins close together ; 
a few blue scales at the base of the wing. Halteres with white 

Legs slender, vestiture steel blue; femora brassy beneath. 
Front tarsi with clear white scales on inner side of second and 
base of third joint; mid tarsi with distinct white scales on 
second and basal two-thirds of third joint all round, apical 
third of third and basal half of fourth joint on one side only; 
hind tarsi with white scales on fourth and basal half of fifth 
joint all round. 

Length about 7 mm. ; wing 7 mm. 

Male : Proboscis long and curved, pointed. Palpi very long, 
longer than the proboscis; terminal joint long and slender, 
slightly curved and tapering to a point ; vestiture metallic violet 
and purple with a sprinkling of brassy scales, apices of all but 
last joint pale violet scaled, beneath all but last joint mostly 
brassy scaled. Vestiture of mesonotum predominatingly dark 
metallic blue with subdorsal coppery stripes. Scutellum cov- 
ered with greenish blue scales. Abdomen deep blue at base, 
shading into reddish purple on sixth, seventh and eighth seg- 
ments, venter golden scaled with median blue line ; lateral cilia- 
tion short. Wings narrow, smoky. Legs slender, vestiture 
dark metallic purple and violet; femora brassy beneath; mid 
tarsi with faint bluish white scales on upper side of second, 
basal third of third joint; hind tarsi with fourth joint white 
all round, fifth joint entirely blue. Claw formula 1.0-1. 0-0.0, 

Length about 7 mm. ; wing 7 mm. 

Hypopygium : Side piece slender, nearly three times as long 
as broad; clasper slender, as long as the side piece, with long 
terminal spine and several small hairs on inner side of outer 
half. Basal lobes distinct, with an apical strong hair, much 
longer than the width of the side piece at this height ; a second 
subapical strong hair more laterally, smaller hairs besides. 
Tenth stemites strongly chitinized, simple. Aedoeagus with 
simple slender mesosome, toothed on inner side, parameres well 
developed with thumblike projection. Basal plates bent down- 



ward to meet parameres. Apodeme connection very narrow. 
Lobes of ninth tergite connected by a broadening of the tergite, 
with flat margin. Hairs of the lobes several, small, pointing 
laterally and outwardly. 

Larva: Head shorter than wide, sides bulging. Antennae 
with very short terminal digits and a few tiny hairs on the 
shaft. Front margin arcuate. Mandible with five teeth, the 
first very strong, the third and fifth smallest, a row of setae 
near. Body smooth. Air tube short, stout, not even twice as 
long as wide, conical, no pecten, a small tuft basally. A plate 
on sides of eighth segment with two stout ciliate hairs on outer 
margin. Anal segment shorter than wide, ringed by the plate, 
which has spinules on its posterior margin ; dorsal tufts a long 
brush on each side ; a single spinulose lateral hair ; ventral brush 
well developed. Anal gills short, bud-shaped. 

This si)ecies is closely related to Meyarhinus trinidadensis 
Dyar and Knab and Meyarhinus moctesuma Dyar and Knab. 
It differs from trinidadensis in the male by the white on the 
hind legs, which is only present on the fourth tarsal segment 
instead of on the fourth and fifth, in the female by the white 
on the mid legs extending on the fourth tarsal joint. Moctezuma 
is only rei)orted so far from Mexico and Central America. 
'Phe typical ring on the hind legs of the male on the fourth 
tarsal joint is present in both species, also the mid tarsi have 
the .same white mark. The hypopygium of the male moen- 
yoensis is very much like trinidadensis, however, and differs 
from moctezuma. The female moengoensis has two and a half 
segments of the mid tarsi white, the female moctezuma only 
one and a half. 

Larvae were found at Moengo, Surinam, feeding on Cleo- 
honnea occulta in the liquid between the leaf cases of Helicoma 
and Ravcnala, 




(Lepidoptera, Noiodontidae) 


About 25 years ago Professor Cockere!! applied the name 
mesUlae to the form of perspicua Grote & Robinson which he 
found at Mesilla, New Mexico. There was no difference in 
the adults from normal perspicua, but the larvae were said to 
differ, resembling ministra, which is to say that the ground 
color was blacker and the lines narrower than usual. I see no 
reason to separate this from robusta Strecker, the larva of 
which has not been described ; but Texas specimens before me, 
from the same region as Strecker’s types, are easily covered by 
the ordinary variation of perspicua. 

More recent collections show that the species extends into 
Arizona and southern California, the forms from these regions 
possessing more marked differences, and also showing a peculiar 
dimorphism. I arrange the forms as follows : 

Datana perspicua perspicua G. 8i R. 

Datana perspicua Grote & Robinson, Proc. Enl. Soc. Phil, iv, 
489, 1865. 

Ranges from New York to the Gulf States and Kansas. 

Datana perspicua robusta Streck. 

Datana robusta Strecker, Lep. Roph & Het., 131, 1872. 

Datana perspicua mesillae Cockerell Psyche, viii, 41. 1897. 

Texas and New Mexico, 

Datana perspicua discalis, new subspecies. 

As in normal perspicua, but the whole fore wing evenly and 
rather densely irrorated with brown scales; reniform a con- 
spicuous brown blotch; subapical streak broad, diffused; some 
purplish scaling at base of wing within the inner line ; outer line 
distinct, rigid; median and faint extra-median lines normal. 

The larva has the ground-color black, the lines narrow, thus 
resembling the larva of perspicua robusta. 



Types, two males, No. 2575)9, U. S. Nat. Mus. ; San Diego, 
California, September 1, 19()(i (G. H. Field). 

Dimorphic form infusa, new. 

Fore wing solidly irrorate with dark brown, appearing of 
this color; inner and outer lines defined by their pale edges; 
two central lines faint, dark ; discal mark distinct, but diffused ; 
subapical line lost. 

Types, two males, No. 25800, U. S. Nat. Mus.; San Diego, 
California, .August 28, 1919 (K. R. Coolidge). 

Datana perspicua eileena, new subspecies. 

Much as in perspicua dtscalis; fore wing more smoothly and 
finely irrorated, the discal mark smaller and more discrete ; lines 
distinct, slender, the sul)apical .streak lost. The insect has a 
smoother, neater api>earance than usual, the ordinary perspicua- 
habitus largely lost. 

Types, two males. No. 25801, U. S. Nat. Mus.; Washington 
Mountains, Arizona (gift of B. Preston Clark); southern 
.Arizona (E. J. Oslar). 

i liniorphic form perfusa, new. 

Fore wing suffused with brown, not as dark as infusa but 
more complete, the lines barely traceable, discal mark absent. 
Fore wing thus uniformly light brown, with faint traces of 
inner and outer darker lines. The female is lighter, pale tan, 
finely and lightly irrorated with brown ; outer margin and apex 
tinged with brown. Inner and outer lines faint ; median fainter 
and extra-median a trace ; no discal marks. Except that I have 
eileena from the same collecting. 1 would be inclined to regard 
this as specifically distinct. 

Tyj)es, male and female. No. 25802. U. S. Nat. Mus.; 
southern Arizona (E. J. Oslar). Unfortunately. Mr. Oslar’s 
s{)ecimens are without exact data. 




Systasea microsticta, new species. 

Fore wing entire, gray-brown with a bronzy reflection; a 
median band of semihyaline white spots, from costa directed 
toward tornus, two small at end of cell, a narrow one out of 
line, a narrow constricted one between veins 2 and 3 and small 
one below; a costo-subapical row of three small spots, before 
which on the costa is a black shade; a similar black shade 
precedes the median row of s\)ots on the costa; a subterminal 
shaded black line, forming a large quadrate blotch on tornus. 
Hind wing the color of fore wing, the sprinkling of white 
scales less through the center of the wing ; a subbasal, median 
and outer band, each composed of two well-separated black 
lines, the spaces l)etween slightly more whitish than the rest 
of the wing. Outer margin excavate opposite discal fold. 
Beneath the wings are shaded with light reddish; markings 
repeated, the fore wing rather broadly white along inner margin. 
Hind wing with the double bands reddish filled, and showing 
more distinctly than above a submarginal macular blackish one, 
with a black spot liefore tornus. Expanse, 28 mm. 

Type, No. 2580.5, U. S. Nat. Mus. ; (iuerrero, Mexico, May, 
1922 (R. Miiller). 

Amblyscirtes mate, new species. 

Black above with bronzy reflection and a light sprinkling of 
pale scales ; fringe pale, dark-checkered at the ends of the veins. 
Below more heavily white-sprinkled, but without other differ- 
ence. Expanse, 25 mm, 1'he antennae are finely ringed with 
white, and with a white mark below before the black club. 

Type, No. 25800, U. S, Nat. Mus. ; Guerrero, Mexico, May, 
1922 (R. Muller), 

Arctia caja virginivir, new subspecies. 

Small, fore wings with the markings of caja caja Linn. 



(Europe) in the male, not so much broken across as to the white 
as in caja phacosoma Butler; in the female the white is ex- 
tensive, so that the wings look white with oval brown spots, 
in four irregular bands and two angular ones on the margin. 
Hind wings red, the black spots as usual, but rather narrow, 
not so full and round as in caja and phaeosoma. Expanse, 
male, 43-49 mm. ; female, 53 mm. 

Tyi)es, male and female, paratypes, two males and female, 
U. S. Nat. Mus. ; “Alaska,” without exact data, but probably 
from one of the coa.stal islands. 

The females indicate a transition toward caja opulenta Ed- 
wards from the Yukon Valley. In the females the accessory 
cell of fore wing is wanting, vein 10 l)eing free, from the cell. 
On this account Mr. W'm. T. M. Forbes, who examined the 
material .some years ago. attached a label “N. gen.?, n. sp.” 
However, in all the males the accessory cell is present; in two 
of them the anastomosis is abnormally near the cell, but in 
the third is in the normal {X)sition. I think, therefore, that the 
absence of the anastomosis in the females is a matter of varia- 
tion, and does not indicate either specific or generic rank. As 
a subspecies, however, the form seems well defined. 

Arctia caja parva Rothschild. 

.A single female which agrees well with this race, described 
from l^abrador, was brought home by Dr. J. M. Aldrich, 
caught by members of his party on a mountain at Windy 
Station on the Alaska Railroad, July 10, 


Celama eurypennis, new species. 

White. Markings brownish black ; a subbasal subcostal 
raised dot ; a costal dot beyond it : costa finely flecked ; an inner 
row of three dots across the wing; discal mark large, raised, 
joined to costa ; an outer line, forming dots on the veins, slightly 
excurved over cell and a little indentation on submedian fold ; 
a broadly wavy faint brown subterminal line; a terminal row 



of shaded dots. Hind wing with a little brown tint on the 
veins and outwardly. Expanse, 22 mm. 

Type, male. No. 25807, U. S. Nat. Mus. ; Provo, Utah, July 
27, 1908 (T. Spaulding). 

Roeselia minuscula eucalyptula, new subspecies 
Larger and paler than minuscula minuscula, the hind wings 
almost white, with a faint discal dot. Expanse, 21-24 mm. 

Types, three males. No. 25808, U. S. Nat. Mus. ; Claremont, 
California (C. W. Metz) ; San Diego, California, May 15, 1912 
(G. H. Field) ; San Diego, California, March 1, 1920 (K. R. 
Coolidge) . 

Roeselia minuscula fuscula Grote. 

Larger and darker than minuscula minuscula, as originally 
stated by Grote. I have a specimen from Colorado which was 
bred from a larva on oak sent me by Mr. E. J. Oslar, but which 
spun in transit. I have another specimen from Las Vegas, 
New Mexico, 1898, which I think came from Prof. C. P. Gil- 
lette, although it is not labelled, and a third, in which the ground 
color is lighter, thus approaching the typical form, Winnipeg, 
Manitoba, July 19, 189? (A. W. Hanham). 

Roeselia minor Dyar. 

Still larger than minuscula fuscula, the wings smooth gray, 
the markings finely written, the outer line well excurved. It is 
possible to consider this as a race of minuscula, though I am 
inclined to regard it as specifically distinct. 

Roeselia bicrenuscula, new species. 

Fore wing shining rather dark gray; three rai.sed brown 
spots in the cell ; lines two, slender, blackish both crenulate, the 
inner regularly arcuate, the outer shortly and bluntly excurved 
between veins 2 and 1 ; subterminal line dark, shaded, wavy, 
followed by whitish. Hind wing pale brown, paler at base. 
Expanse, 28 mm. 

Type, female. No. 25809, U. S. Nat. Mus. ; “Arizona"’ without 
definite locality (Schaus collection). 



Near conspicua Dyar, but the markings very distinctly writ- 
ten, whereas that is faintly and obscurely marked. 

Roeselia conspicua Dyar. 

1 consider this a distinct species, and do not follow Sir 
Cieorge Hampson and others who refer it as a synonym to 
mmuscula fuscula, 

Roeselia varia Barnes & Lindsey. 

1* have a cotype, by the kindness of the authors of the species, 
from the Chiricahiia Mountains, Arizona. A number of speci- 
mens were sent me some years ago by Mr. Oslar from the 
Huachuca Mountains, August 21-25, 1903 (E. J. Oslar). It 
resembles minor most nearly, the outer line being more sharply 
dentiailate and the ground color darker. 

Roeselia extusata, new species. 

Fore wing gray, dark, without any purplish tint; a square 
blackish shade in outer half of cell, reaching costa, emarginate 
without and showing a white discal mark. Lines dentate, the 
inner excurved, the outer strongly excurved around cell; sub- 
terminal line crenulate and slightly waved, pale, submacular, 
edged darker within. Fringe checkered. Hind wing dark 
])rown. Expanse, 25 mm. 

1'v}>e, female, No. 25810, U. S. Nat. Mus. ; Ramsey County, 
Arizona, 5800 feet, August 1, 1910 (K. R. Coolidge).

the Schaus collection. “Arizona,’’ without definite locality. 

Subfamily HADENINAE 
Trichestra bicatenata, new species. 

Fore wing purplish gray, the median space contrastingly 
darker ; costa narrowly light, with several black flecks ; subbasal 
line black, crenulate, crossed by a basal dash ; a red shade on 



submedian. Inner line curved, outer excurved over cell, both 
faintly doubled, dark, smooth; claviform black, solid, thick; 
orbicular a large ringlet filled by ground-color, obscure; reni- 
form distinct, white-edged, dark filled ; subterminal line whitish, 
faintly yellowish, powdery, submacular, distinct in the light 
purplish terminal field; terminal line a shade darker than the 
ground, broad. Hind wing pale in the disk, veins and terminal 
area, purplish gray. Expanse, 28 mm. 

, Type, female. No. 2«58n, U. S. Nat. Mus. ; Mexico City, 
Mexico, October, 1921 (R. Muller).

Fore wing orange-ocherous, powdered with dark scales ; inner 
line thrice arcuate, faintly doubled; median shade-line bent on 
median vein; outer line crenulate, with lines on the veins to 
margin; subterminal line a little wavy; a black dot for clavi- 
form; orbicular and reniform narrowly dark outlined, the 
latter with two white specks in the lower edge. The lines are 
relatively inconspicuous, and tend to outline the paler contrast- 
ing areas, which are the reniform, orbicular, and an outer 
rounded macular band, formed of the subterminal space. Hind 
wing dark bronzy brown, the apex red-brown. Expanse, 20 mm. 

Type, female. No. 25813, U. S. Nat. Mus.; Zacualpan, 
Mexico, April, 1921 (R. Muller). 

Hydroeciodes tintebela, new species. 

Fore wing orange-ocher, marked with red-brown, the terminal 
space being solidly of this color, the cell largely filled with it, 
and the distinct angled median shade-line also so colored. Lines 



red-brown; inner and subbasal of broad arcs, narrow; clavi- 
form similar to a loop of the inner line; costa mottled, and 
with little pale dashes outwardly; orbicular outlined; reniform 
cut by lines on the veins, the lower of these marginal spots 
whitish tinged ; outer line crenulate on the veins, excurved

pale. Expanse, 27 mm. 

Types, two males, No. 25814, U. S. Nat. Mus. ; Zacualpan, 
Mexico, December, 1921 (R. Muller). 

Oligia iridis, new species. 

Close to hridghanti Grote & Robinson, of the same size, 
darker, the median space clear red-purple, more uniform and 
brighter than in bridghami. Hind wings dark fuscous, lighter 
at base, with a faint (»uter dark line, relieved by a narrow pale 
shade beyond. Expanse, 20 22 mm. 

Ty]>es, male and female, U. S. Nat. Mus. ; without locality 
(Coll. J. B. Smith), labelled **Had, Bridghami G. & R.” in 
Smith’s handwriting. In his catalogue (Bull. 44, U. S. Nat. 
Mus., 1*11, 189:1), the late John B. Smith gives the habitat of 
bridghami as ‘‘Eastern States, Massachusetts in July,’" and as 
these specimens were doubtless before him at the time, their 
origin must be included in this statement. 

Bagisara gustata, new species. 

Near biixea Grote, yellower, the fore wing distinctly yellow, 
with the lines faint, but the terminal burnt-brown shade very 
distinct. Expanse, 28 :10 mm. 

Types, male and female, U. S. Nat. Mus.; Chiricahua 
Mountains, and Huachuca Mountains, Arizona (gift of Dr. 
William Barnes). 

Oslaria haematosticta, new species. 

Frontal process large, with raised edges, the lower rim 
arcuate, the upper straight across, produced into a short plate 
with a slight point in the middle. Fore wing brownish yellow. 



irrorate with dark red at base and along costa; inner line 
diffused, dark red, obsolete across cell; outer line narrow, 
mustard-brown, faint, excurved over cell; reniform elliptical, 
mustard-brown, faint. Hind wing rather dark fuscous with 
pale fringe. Expanse, 19 mm. 

Type, female, U. S. Nat. Mus. ; Mesilla Park, New Mexico, 
at light, July 8, 1897 (T. D. A. Cockerell). 

Neumogenia bellamusa, new subspecies. 

Fore wing metallic green-bronze ; a wide straight costal stripe 
of white, shading to gray on outer half ; a white streak on 
median vein, widening at end of cell, projected a little on veins 
3 and 6, following vein 4 to termen, fringe gray, with white 
interline. Hind wing lightly shaded with gray-brown. Expanse, 
male, 34 mm.; female, 32 mm. 

Types, male and female, U. S. Nat. Mus.; Zacualpan, 
Mexico, July, 1913 (R. Muller) ; Iguala, Guerrero, Mexico. 
June, 1906 (W. Schaus). 

This differs from dbavena Ottolengui, of which it may be 
considered a subspecies, in the greater extent of the white 
markings. Smithi Druce, from Mexico, differs in a similar 
way from its Arizona subspecies, sagittalba Ottolengui. On 
the other hand, coronides Druce from Mexico has less of 
white marking than its Arizona form, pendula Ottolengui. 
N, poetica Grote is specifically distinct from the three, and no 
Mexican representative of it is at present known.

Thurberiphaga catilina Dyar, Ins. Ins. Mens., vii, 188, 1920. 

The figures given by Barnes & McDunnough seem undoubt- 
edly to represent the insect described by me. 

Dasyblemma, new genus. 

- Falls with Catoblemma Hampson (Cat. Lep. Phal, Brit, Mus., 



X, 36, 1910), but the palpi have the third joint long, slender, 

Dasyblcmma straminea, new species. 

Fore wing long, creamy, tinged with straw-color; a black 
line along costal edge to beyond middle ; inner line dotted, bent 
at right angles on median fold, discal mark a clouded oval;

California, October 17, 1920 (K. R. Coolidge). 

Cham}rris obscura, new species. 

Similar to cerintha Treitschke, smaller, the median band of 
fore wing darker, nearly as dark as the terminal markings. 
Hind wing fuscous, paler at the base, with a dark discal dot. 
This is larger than sirius Barnes & McDunnough, more of the 
cerintha type, though obviously distinct. Expanse, 26 mm. 

Type, female, U. S. Nat. Mus.; Thomasville, Georgia (Mrs. 
A. P. Taylor). 

Lirimiris truncata Ilerrich-Schaeffer. 

This species must be added to the North American list on 
the strength of a specimen before me from Arizona. The 
larva was collected in the Santa Rita Mountains, Arizona, on 
Thurhcria thcspeoides by Mr. W. D. Pierce, and the adult was 
bred by Mr. B. R. Coad, emerging September 14, 1913, The 
tough cocoon of brown silk accompanies the specimen, evidently 
spun in a crevice of the breeding-cage. 

Heterocampa varia Walker. 

Heterocampa varia Walker, Cat. Brit. Mus., v, 1023, 1855. 
Disphragis georgiana Dyar, Ins. Ins. Mens., ix, 139, 1921. 
Disphragis baryspus Dyar, Ins. Ins. Mens., ix, 141, 1921. 

Mr. F. H. Benjamin has shown me a specimen compared 
with Walker's type by Dr. J. McDunnough, which matches 



both georgiana and baryspus. The former are bred specimens, 
somewhat dwarfed, the latter a fully developed captured speci- 
men. I do not now think there is any other difference between 
them, and both will fall to varia Walker, which is now posi- 
tively identified.

(Diptera, CuHcidae) 


The Yellowstone National Park occupies a very large area 
in northern Wyoming, lapping over for a short distance into 
Montana. The Park was established to conserve the remarkable 
hot-water formations and geysers; but these liave no interest 
in the present connection, as the hot water is not a factor in 
breeding conditions. The area of the Park embraces the crests 
of the Rockies, of which the higher altitudes are well forested. 
The lower slopes, however, are bare, and continuous with the 
arid country below. The Canadian fauna follows the forested 
region of the higher altitudes. The fauna of the arid region 
runs up the slopes, and there is often an interesting succession 
of species, as will be noted in detail under the specific headings 


Collections were made at six stations, resulting in 3,143 
si>ecimens of mosquitoe.s. These stations were as follows: 

Livingston, Montana. On the Yellowstone River at the 
|K)int where the stream emerges from the hills into the plain. 
The altitude is 1,150 feet above sea. The river is running 
rapidly, and has formed small gravelly plains or deltas, which 
are densely grown up with cottonwoods and willows. In the 
cover of this vegetation, at time of flood, many small pools and 
channels of water appear by seepage from the main stream. 
The country surrounding is hilly, bare, except for a desert 
vegetation. Collections were made in the timber and also in 
the open ; but most of the specimens came to hand in the timber. 
A'cdes vexans Meig. predominated, with A, mutatus Dyar a 
close second ; A, idahoensis Theob. was third with A, hirsuteron 
fourth, though far in the rear. These captures indicate normal 
flood conditions in the valley as would exist at lower altitudes, 
’except for the presence of A, mutatus, a species peculiar to 



the flood-pools of the swift streams of the Rocky Mountain 
watershed. The fauna here is essentially of the arid valley type. 
The small size of the flood-pools has evidently excluded aldrichi 
and favored the presence of hirsuterofi. The details of the 
si>ecies taken are shown in the accompanying table, in per- 
centages (see page 4<i)- 

Mammoth Hot Springs, Wyoming. This station is sit- 
uated some 60 miles farther up the Yellowstone, but on a small 
tributary stream, the Gardiner River. The altitude is 6,387 feet. 
The station is on a bench high above the river, in open sage- 
brush covered hillsides. The slopes rise abruptly from the 
river, which is in the bottom of a deep gorge, and extend far 
above the station, undulating and irregular. In the hollows be- 
tween are occasionally small temporary pools or ponds. 

Tlie breeding of mosquitoes was practically confined to the 
flood-pools in the river-bed of the Gardiner River. The pools 
on the hillsides seem to produce practically nothing in the way 
of mosquitoes, except Culiseta and Culex, which are wholly 
negligible economically in this region. A, mutatus Dyar pre- 
dominated, and A, impiger Walk, and A. communis DeGeer 
.second and third, respectively. The fauna of the plains is now 
definitely left behind. The fauna of the stream itself pre- 
dominates, with a strong admixture of the Canadian fauna, 
although timber-line is not yet in sight. A. idahoensis of the 
arid plains persists in small proportion. Reference is made to 
the detailed table. 

Camp Roosevelt, Wyoming. I'his station is on the Yel- 
lowstone River, alx)ut halfway between Mammoth and the 
Canyon, at an altitude of about 7,000 feet. Heavy forest 
covers the upper hills, but the lower hills bordering the river 
are bare. The river here flows through a steep gorge without 
deltas in the vicinity, although the captures indicate that there 
are flood-pools at no great distance. The camp itself is in the 
edge of the forest, overlooking the open hills which obscure 
a view of the river itself. A small stream, called Lost Creek, 
comes out of the high forest and soaks into a marshy plain, now 


INSKCUTOR inscitm: menstruus 

open, although perhaps once wooded, to emerge below and 
empty into the Yellowstone a mile or more downstream. 

Of the mosquitoes, A, idahoensis Theob. predominated; but 
this was largely due to the results of an automobile ride across 
the river into open country some 4 miles up the Lamar River, 
a tributary of the Yellowstone. Mr. W. C. Troutman of the 
Tower Falls Forest-Ranger Station had informed us that mos- 
quitoes were plentiful in this region, and undertook to act as 
guide. His statements were verified in the existence of a con- 
siderable number of this species resting in the rabbit-brush and 
sage of the open hillsides. Mosquitoes at the camp were un- 
happily scarce at the time of visit, to one intent on collecting. 

Second in abundance was A, puUatus Coq., and A, fitchii 
F. & Y. was third. The Canadian fauna is thus definitely 
established with the proximity of the forest, although its 
normal proportions are distorted. The paucity of captures 
had something to do with this. The camp, in favorable seasons, 
is well situated to enjoy the mosquitoes of both mountains and 
plain, or perhaps we should say to suffer from them. 

Old Faithful, Upper Geyser Basin. This remarkable 
geyser gives its name to the station. Altitude, 7,3iH feet, on 
a small stream, the Firehole River, flowing into the Madison 
River, with outlet to the west. The hills are forested, although 
the valley is narrowly open, largely due to the presence of the 
hot water formations, so destructive to vegetation. Two large 
marshy |X)nds are fed by a small rill that drains into the Firehole 
River. This latter stream is swift and turbulent, with small 
deltas shaded by forest. 

No one s])ecies of mosquito predominated strongly, the Cana- 
dian fauna appearing here well balanced. Most numerous was 
A. fitchii F. & Y., although on account of the practical impossi- 
bility of separating captured females of this from A, excrucians 
Walk., the count may have erred. However, the ring-legged 
si^ecies of this group certainly predominated, a fact easily at- 
tributable to the presence of the large grassy-margined ponds 
above mentioned. Second in abundance was A, communis 

insecutor insciti^ menstruus 


DeGeer, a species destined at slightly higher altitudes to strongly 
predominate, well justifying its name. The table gives details. 

Canyon Station. This is on the Yellowstone where the 
river passes through a short but deep canyon, forming two 
wonderful falls. The hotel is on one side of the river, the 
camp on the other, the altitude being given as 7,710 feet. The 
country is very steep, hills rising to great heights all about, and 
the deep canyon below. Most of the country is forested, al- 
though considerable areas are open of both hill and valley ; but 
the open country is here grassy and not with a desert vegetation, 
owing to the altitude. In the hollows of the hills, both under 
forest and in the open, but more so in the open, certain shallow 
depressions are early filled by snow-water. These are recog- 
nizable even late in the season by the yellow coarse nature of 
the grass. They are the favored breeding-places of A, com- 
munis, shared in les.ser proportion by other species. It is not 
.surprising, therefore, to find that this species largely predomi- 
nated, forming half of the captures. A. fitchii F. & Y. was 
second and A. cataphylla Dyar third. The fauna thus remains 
es.sentially Canadian; l)ut the increase in cataphylla gives it a 
more arctic complexion, reminding one of conditions in the 
Yukon, as befits the altitude. 

[ was particularly interested in the succession of the species 
A, idahoensis and A. spenccri, A. idahoensis is predominant 
in the dry plains of Montana, while farther to the north, in 
Canada, the plains becoming grassy, spcnceri replaces it. Here 
idahoensis persisted strongly up' to Camp Roosevelt, strayed as 
far as the Canyon, but was then replaced by spenceri, altitude 
corresponding strictly with latitude as affecting the distribution. 

Yellowstone Lake, Wyoming. An enormous lake, the 
headwaters of the Yellowstone River, altitude 7,788 feet. This 
does not appear much higher than the Canyon, but is so in 
effect, the country l)eing here of this level as the lowest, 
whereas the altitude given for the Canyon is presumably that 
of the hotel, perched high on a hillside. The country at the 
Lake is forested. The forest, however, is not moist, and breed- 



ing places not abundant. Shallow early pools of the character 
above described occur and also small receptacles formed by the 
roots of overturned trees. The Canadian fauna obtained com- 
pletely. A, communis formed over half of the captures, with 
cataphytla, pullatus and pionips Dyar close together and all 
together not equalling the numbers of the communis. The con- 
siderable number of pionips was due to breeding. The species 
had scarcely begun to fly at the time of visit. At this station, 
Culiseta alaskaensis Ludlow was taken, the most characteris- 
tically northern species of the fauna. The ring-legged A’edes 
have ceased to figure as an important ingredient of the fauna. 


Aedes fitchii Felt & Young. 

This is the true fitchii, having the male hyix)pygium with a 
strong basal spine, and not the form mimesis Dyar of the 
Montana valleys, in which this spine is weaker and the filament 
of the claspette longer. The specimens from Livingston* Mon- 
tana, have been classified here; but no males were taken, and 
the form occurring there may be mimesis. In the forested 
country* fitchii was very common, forming about 20 per cent of 
the total captures. The distribution of the determinations be- 
tween this si>ecies and cxcruchws is the result of pure 
work. Every character for separation that I have tried to fol- 
low out has broken down. 

Aedes mutatus Dyar. 

This little ring-legged s|>ecies is generally separable from 
fitchii by its smaller size and reduction of the white markings. 
It breeds in the little pools in the flood-deltas of swift mountain 
rivers. This is a racial form of the Californian A, increpitus 
Dyar, In the male hypopygium, the expansion of the filament 
of the claspette occurs almost exactly at the middle. The male 
from Drummond, Montana (Proc. U. S. Nat Mus., Ixii* 73* 
1922) causes a difficulty, for the expansion is towards the base, 
and this influenced my original description (Ins. Ins. Mens., vii* 
25, 1919) ; but the accumulation of material forces me to regard 



this specimen as an abnormality, or at least a variation* The 
slide shows also an oblique chitinized piece in the basal lobe, 
which does not normally occur. In the Park, the species dimin- 
ished at the higher stations and finally disappeared. 

Aedes cxcrucians Walker. 

The species was positively determined, both by males and 
larvae. I have credited it with only a small occurrence, less 
than 4 per cent of the captures at the four upper stations; but 
the actual occurrence may have been larger. A portion of the 
fitch a very probably belong here. 

Aedes punctor Kirby. 

Positively identified by males and larvae, but occurring in 
small pro|X)rtion of captured adults. The variation of the 
abundant communis overlaps this species, so that some punctor 
may have been erroneously included therewith. In my paper 
on the mosquitoes of the Glacier National Park (Ins. Ins. 
ilens., X, 82, 1922), I* stated that this species apparently does 
not occur. As it occurs in Wyoming, farther south along the 
same mountain range, the probability is that it was missed in 
the collecting at Glacier. This might easily happen, as the 
collecting there was done late in the season. 

Aedes hirsuteron Theobald. 

Occurred only in the small flood-pools at Living.ston, Mon- 
tana. Specimens were bred from such pools, and the adults 
were not taken on the wing. The occurrence of this species 
instead of aldrichi at this station is interesting. 

Aedes idahoensis Theobald. 

Predominant in the dry open country. A, dorsalis Meig. 
and A. nigromaculis Lud, occurred with it, but in much smaller 
proportion. At altitudes where grass replaces the desert vege- 
tation in open country, this species ceased. 

Aedes spenceri I'heobald. 

Found rarely at high altitudes in grassy open country. This 
species is characteristic of the grassy prairies of Canada, North 



Dakota and Minnesota. I did not find the species in the Glacier 
National Park, probably because collecting was not done at 
sufficiently high altitudes. 

Aedes communis DeGeer. 

As the form lazarensis did not occur, I have used the name 
communis instead of the communis lazarensis of the Glacier 
Park paper. In the specimens that approach nearest to laza- 
rensis, the mesonotum is dark brown rather than yellow. This 
general darkening persists, and when the dark lines are lost, 
the mesonotum is uniformly dark brown, exactly as in normal 
intrudens. Many strange freaks in coloration occur, resembling 
hybrids with this or that. In the Glacier Park paper, 1 definitely 
referred these as hybrids, and cited two males which I took to 
be crosses between lazarensis and intrudens, I think now that 
these males are pullatus, with some variation and irregularity 
in the structures, which may perhaps frequently occur. As 
long as this explanation is possible, ] prefer to abandon the 
citation of natural hybrids, for the present at least. A, com- 
munis was the dominant species at all the higher camps. 

Aedes pionips Dyar. 

Found at the higher camps. The absence of any record at 
the Canyon station is due to the distance of the breeding 
grounds there and the fact that the species was not flying at the 
time. This species breeds in the largest of the temporary 
spring jxjols, some of them resembling little lakes, though ulti- 
mately going dr}’. It was also found in the hollows formed 
by overturned trees. The large larvae develop slowly, and are 
not emerged as adults and distributed till mid-summer. At 
the Canyon, typical pionips pools were observed, but some three 
miles from camp, and they were not visited for collecting. 

Aedes cataphylla Dyar. 

Present at all the stations above (>,000 feet, more abundant 
at the higher ones. It apparently breeds early in the communis 
pools and similar locations. Most of the specimens taken were 
very much worn. 



ASdes impiger Walker. 

This occurs with the preceding in smaller proportion. A 
breeding-hole of this species was discovered at Mammoth in the 
bed of the Gardiner River and a series bred, which accounts 
for the exceptionally large proportion of impiger recorded for 
that station. 

Ai^des dorsalis Meigen. 

I'his characteristic prairie form occurred at all stations in 
the open, diminishing as the altitude increased. My record 
should have shown about 2 per cent at Mammoth, but I did 
not happen to catch a specimen there. The collecting was 
small and sporadic at that station. 

Aedes canadensis Theobald. 

This species probably extends throughout the region, dimin- 
ishing in numbers upward; but in small proportion, and it is 
late in emerging. It was missed, therefore, at several stations 
where it may occasionally be found. 

Aedes pullatus Coquillett. 

C)ccurring at all the stations, increasing in numbers upward. 
The larger record at Camp Roosevelt is due to a small but at 
the time exciting flight of this species, which occurred one 
evening after a strenuous day of hard search with very small 
results. The small record at the Canyon station, on the other 
hand, is due to the fact that we did not find any breeding-pools 
of the si)ecies there, and the record depends only on captured 
specimens. This species develops very late, and at all the sta- 
tions was only in part on the wing. 

Aedes intrudens Dyar. 

I am not certain of the occurrence. No male was obtained, 
and the recorded specimens may all be dark forms of communis. 
However, I think that the species probably occurs. 

ASdes diantaeus Howard, Dyar & Knab. 

Positively identified by a male, but very rare. It was noted 
only at the Canyon station. 



Aedes nigromaculis Ludlow. 

This typically prairie species was not encountered above Liv- 
ingston, Montana. 

A’cdes vcxans M eigen. 

Very common at Livingston, then immediately disappearing. 
The single specimen taken at Yellowstone Lake, the highest 
station, seems quite out of place. 1 do not think that any mis- 
take occurred in the record, although this may be possible. 

Aedes cinereus Meigen. 

At all stations, high and low, but never common. Its apparent 
absences at Mammoth and Camp Roosevelt are attributable to 
the accidents of collecting. The adults closely hug their 
breeding-places, and so are easily missed in collecting at large. 

Aedes cacothius, new species. 

Small, compact; mesonotum coarsely scaled, dark yellowish 
gray with paired central lines of moderate width and posterior 
side lines of black, overlaid with red-brown ; abdomen black 
above, with narrow segmental basal white bands, divided in the 
middle, only slightly expanding laterally; venter whitish gray 
scaled, the two basal segments unmarked, the posterior seg- 
ments with posterior transverse black bars and a median black 
wedge, which runs forward from the black bar on each seg- 
ment nearly or quite to the anterior border. Wing-veins black 
scaled, some whitish scales at base and subcostally; scales at 
bases of third and fourth veins forming small spots. Legs 
black, with many white scales intermixed; femora and tibiae 
below largely whitish. Claws toothed on all feet. 

Types, six females, No. 1^5952, U. S. Nat. Mus. ; Shoshone 
Point, 8,200 feet, Yellowstone National Park, Wyoming, June 
27, 1922 (H. G. Dyar). 

The specimens were taken biting near noon in bright sun- 
light on a road on an exposed hillside, while stopping a few 
minutes to enjoy the extended view to be had at this point near 
the crest of the divide. 



It is thought that this may be the Rocky Mountain represen- 
tative of Acdes ventrovittis Dyar of the high elevations in the 
Sierras. The species is of the size and general appearance of 
A, cataphylla, as that occurs in the Yellowstone Park; but the 
distinct stripes on the mesonotum seem to preclude a reference 
to that species. The wing veins are distinctly black and uni- 
form, thus excluding both spenceri and idahoensis; idahoensis 
is further excluded by the altitude, and spenceri by the narrow 
discrete abdominal tending. The exact status of the form, 
however, must await further exploration. Nothing like it was 
taken at the lower levels. 

Culiseta inomatus WilHston. 

This species completely replaces incidcns Thomson of the 
northern Rockies, and the same condition evidently prevails in 
the Glacier Park. The species occurs everywhere, except at 
Livingston (where there was no permanent water), breeding 
abundantly in the extinct hot-springs, which have grown cold 
and dirty, with slight emission of gas. Also in marshes, espe- 
cially the sulphurous and dirty ones. The adults are rare. The 
larger proportion noted at Mammoth was due to the breeding 
of a series. 

Culiseta alaskaensis Ludlow. 

A single specimen was taken at the Lake station while sitting 
out in the evening at the ‘‘bear dump” watching the antics of 
these animals. As the record is wholly new to the United 
States and Wyoming, the exact date may be given, June 20, 
1 922. We think that we saw another specimen at Old Faithful ; 
but it flew away at the first motion to catch it and never 

Culex tarsaiis Coquillett. 

This species also favored the extinct hot-springs and marshes, 
and when one of these was found full of larvae, so that there 
seemed to be as many larvae as water, the impression of extreme 
abundance was created. But the adults never came to bite. 



Good breeding places were really very scarce, so that as a 
whole the species is rare. 

1 am especially indebted to Mr. Horace M. Albright, Super- 
intendent of the Park, who was good enough to defray my 
expenses and those of Mrs. Dyar through the Park in return 
for our recommendations as to how the mosquitoes could be

{Dipt era, CuKridae) 


While primarily engaged in conservation work during the 
early spring of 190] the writer found a species of Anopheles 
on Terrebonne Bay, Louisiana, which appeared unusual to him 
on account of having unspotted wings. This specimen was 
sent to Washington, and is in the United States National 
Museum, forming the basis of the record in Howard, Dyar & 
Knab’s “Mosquitoes of North and Central America and the 
West Indies” of Anopheles walkeri Theobald from Terrebonne, 
Louisiana (vol. iv, p. lO:!.")). Thus the matter rested until the 
spring of 1928. At this time a large number of mosquitoes 
were sent me for identification from Gulfport, Mississippi, and 
among them were badly mutilated specimens of this species. 
This reawakened interest, and it was deemed advisable to 
revisit the original locality, to determine if possible the preva- 
lence, distribution and life cycle of this species, and especially 
its possible role in the tramsmission of malaria. 

From the mouth of the Atchafalaya to Terrelionne the boat 
passed through a now almost uninhabited region of larger and 
smaller islands, lifeless, treeless, and desolate in the extreme. 
F.ven the fisher-people who formerly populated this region have 
deserted it and moved their families from 30 to 40 miles inland, 
out of reach of ever-threatening storms and tidal waves. 
Extremely fertile, well-settled and cultivated sections were ren- 
dered barren in a single night by the last storm, which struck 


that r^ion in September, 1909, and they have remained de- 
serted ever since. 

Prom information gathered, it appears that before the catas- 
trophe of 1909, some of the settlements used to suffer quite 
regularly from malarial infection. 

On the morning after tying up to the shore, even before 
daybreak, the cabin was swarming with mosquitoes. Only 
three species could be identified, the Anopheles in question, 
A. crucians and Aedes solUcitans. Of these, the first was by 
far the most numerous. 

After carefully examining over one hundred perfect speci- 
mens, I became convinced that the mosquito in question cannot 
be Anopheles walkeri Theobald, but conforms in most respects 
with the description of Anopheles atropos Dyar and Knab, 
described from the Florida Keys. This determination has, 
therefore, been adopted. 

In its general appearance. Anopheles atropos is a very dark, 
almost black insect, and only when viewed closely and in strong 
light does its coloration become distinct. Its normal resting 
position is different from that of other species. While resting 
on a vertical surface, the body in A. crucians, etc., is nearly 
at a right angle; but that of A. atropos is held at an angle of 
45 degrees. In its attack upon man it is direct and vicious. 

An immediate search was made for breeding places. We 
destroyed practically all the mosquitoes on the boat and ex- 
plored the shore. Large and small puddles of water were care- 
fully searched in all directions without avail. No algae were 
present in the pools, which had been flooded by high water. 
Sitting among the tall grass drew no Anopheles, though AMes 
solKcitans was plentiful; but when we had returned to the 
boat, the Anopheles were there in hundreds. Only one male 
was seen, and the conclusion was reached that the species did 
not breed in the immediate vicinity. Artificial breeding experi- 
ments were therefore undertaken. 

Females were taken, allowed to fill themselves with blood, 
and placed in a large wire cs^e. Specimens kept, but which 



had not been fed, usually died in 24 hours. The others mostly 
survived the journey back to New Orleans, being supplied with 
moistened sugar in addition to the blood-meal. Eggs began 
to be deposited five days after capture, an abnormally long time, 
the reason for which will appear. Of these, a certain number 
failed to hatch, probably being infertile. The greatest number 
of eggs determined for one female was 199 and the least 83. 
The eggs resemble those of A. quadrimaculatus, with about 30 
cells in each lateral float. The larvae hatched from 40 to 48 
hours after oviposition, whereas in A, crucians and quadri- 
maculatus, the average time is about 72 hours. There is indi- 
cation that the eggs are capable of withstanding desiccation. 
Some which adhered to the sides of the jar and were left above 
the water level by evaporation hatched when coming in contact 
with the water again. The following experiment seems to indi- 
cate that the eggs are naturally deposited in wet mud and not 
on the water, as with crucians and quadrimaculatus. A number 
of females were placed in a large jar, the bottom of which had 
been covered with a cloth moistened with salt water. In a few 
hours several hundred eggs had been laid on the cloth ; but in a 
jar with a similar number of females, but which contained three 
inches of sea water, no eggs were deposited for four days. 
All the females in the two experiments had been blood-fed 
within a period of not more tlian an hour. 

At first, several difficulties were encountered in raising the 
larvae. It was not at first suspected that the species is addicted 
to sea water, and this was not supplied. Again it was found 
that predacious insects had been introduced with the material in- 
tended for food. A second trip was therefore made to the breed- 
ing grounds and some mud, overgrown with a Chlorococcus^ 
like alga and sea water were taken to the laboratory. In th^ 
meantime the above-described experiment had been tried, and 
the mud-breeding habit was more than suspected. To test this, 
a quantity of Potamogeton pusillus and Cladophora fracta was 
boiled for about twenty minutes. After this had stood, it 
became covered with a slimy scum and simply smelt to the 



heavens. On microscopic examination the larger proportion of 
the scum was found to consist of a viscid slime and hundreds 
of Vorticella. Some of the marsh mud was now spread on 
the bottom of a shallow glass dish and small quantities of the 
boiled food were scattered about. Only enough sea water was 
used to barely cover the mud. 

The larvae were then about 48 hours old, and did not 
measure 1 mm. when put in the dish. They fairly reveled in 
the mud, tearing away at the slimy scum, shaking off the 
surplus and swallowing quantities apparently out of all pro- 
portion to their size. Their growth was now fairly propor- 
tionate to their voracity. Adults were now obtained 14 days 
after hatching of the egg, whereas in the first attempt, under 
ordinary conditions, the development had taken 22 days longer. 

The conclusion was reached that the larvae are almost ex- 
clusively mud denizens and mud feeders. In order for them 
to thrive, the volume of water must be reduced to a minimum, 
and only when they are replete with food will they assume 
what is usually the characteristic position of Anopheles larvae. 
Furthermore, they seem to be gregarious, and prefer to con- 
gregate in groups, for if separated, they will collect together 
again in an hour’s time or less. 

When first hatched the larva measures less than 1 mm. It is 
quite colorless and transparent, with the exception of its large 
head, which is dark. Gradually the color deepens, and at the 
end of the third day it sheds its first skin and becomes dark 
brown, with white transverse bands. These crossbands consist 
of large white spots, usually two on each s^;ment. The broad 
band on the anterior part of the thorax is made up of four spots. 
In this conspicuous coloration the larva remains until after 
the second moult, which occurs approximately three days after 
the first. The color now changes to dark gray, while the large 
white spots are no longer as conspicuous, and the majority of 
them seem to have dissolved into minute white dots, dispersed 
over the entire dark median area of each segment. After the 
third moult the larger spots disappear completely, and only 



the minute ones remain, making the larva almost mud-colored, 
and rather hard to distinguish from its surroundings. After 
the fotifth moult the larva becomes mature. Length, 8 to 8.5 
mm. Color, gray or yellowish gray, with a dark median stripe. 
The head is ocherous with dark brown markings, the pattern of 
which is constant, and while other variations occur, the essential 
features of the pattern remain. There is always a more or 
less broad band of deep brown just beyond the base of the 
antennae, and another one marking off the line between the 
vertex and the occiput. From this band arises a semicircular 
loop, which extends into the occipital region. In the center of 
this semicircle and attached to the posterior matgin of the 
crossband is a larger or smaller spot of the same color. The 
posterior foramenal border of the skull is edged, as it is in all 
Anopheline larvae, with a dark brown margin, which, however, 
is interrupted in the middle dorsally and ventrally. 

[ Note by the editor. Dr. Beyer’s series of colored drawit^s 
of adult and structural details of the larvae cannot be repro- 
duced on account of the question of expense. I have therefore 
redrawn the more important details, more especially for com- 
parison with the account of A. walkcri Theobald by Matheson 
and Shannon which appears herewith. Dr. Beyer’s descriptions 
of the structures have also been omitted, as these refer par- 
ticularly to the colored drawings, and are not comparative with 
the allied northern form. The omitted drawings include one 
of the genitalia, which, however, gives insufficient detail for 
the close comparisons requisite in this case. Dr. F. M. Root 
has kindly compared the slides of atropos and tvalkeri, and 
finds small, but specific differences. These will be given in a 
forthcoming paper by him.] 

In the life of the adult insect there are several phases which 
remain unexplained so far. In the first place, where do they 
actually deposit their eggs? As already related, laboratory 
experiments showed them to be mud-feeders in the larval stage. 
On both excursions into their breeding grounds, almost every 
foot of land was under water to the depth of 6 inches and 



more, and yet no larvae could be found, while the adults 
swarmed in countless niunbers. 

Secondly, where do the adults keep diemselves during the 
daytime? None could be seen 6 feet away from the boat, 
while at the same time they were gathering on board in broad 

In regard to the distribution of the spedes, ascending Bayou 
Terrebonne, female adults came on board the boat as far as 10 
miles inland, when they were suddenly replaced by Anopheles 
crucians and quadrimaculatus. What is the reason for this 
sharply drawn limit? High tide and pure salt water reaches 
considerably beyond this 10-mile limit at times. 

Compared with other Anopheles, atropos seems to have little 
or no power of endurance outside the limits of its habitat. 
Unlike most species, it can, apparently, not endure confinement. 
On this account, all efforts to determine its vectorship of malaria 
were rendered futile, because no females could be kept aliv^ 
long enough to be fed on malarial patients. Only diose speci- 
mens which had been blood-fed at capture survived the return 


(Diptera, CuHcidae) 


No observations are on record of the swarming of this species. 
The following is therefore presented : 

At Warroad, Minnesota, on the evening of May 21, 1922, 
sitting in a swampy place in the edge of woods, a swarm was 
noticed in the air near the top of a willow bush. I was on the 
lookout for Aedes riparius, and fancied that this was a swarm of 
dus species. An effort was made to catch some, but as ! had 
<mly h diort-handled net with me and the swarm was high, 1 
fidkd to get any, Pireparing to make a second effort, to my 
surprise, the swarm drifted away from the woods, still intact, 



and was lost to sight over an open meadow. I went back to sit 
down on my 1(^ again, but immediately noticed another swarm, 
probably containing 50 individuals. This was high like the 
other and was slowly drifting away from the woods toward the 
willow bush. It passed this and went out on the meadow. A 
third swarm followed immediately, plainly emerging from the 
woods, and by a violent effort some specimens were captured 
from it. It was evident at once that the species was not riparius, 
but cinereoborealts, whose strange behavior it had been my good 
fortune to observe. Swarm followed swarm in leisurely suc- 
cession, each one following the last out over the open meadow 
and was lost to sight. The phenomenon lasted perhaps half an 
hour, until it was too dark to see, and may have continued after 
dark. Many hundred males must have thus passed over my 
head. I was unable to repeat the observation on the following 
or any other night. No more males appeared. Even the fe- 
males presently began to be scarce, having before bitten rather 
freely. It is thought that these swarms of males were engaged 
in the act of distribution, perhaps to finish their swarming in 
small clusters at remote distances. I have not observed such 
a performance in any other species 


(Dtptera, Culiadac) 


During the past two seasons the writers have undertaken, in 
connection with other investigations, the rearing of Culicidae. 
In the course of this work, Europe's chief malaria carrier, 
/i, fnacuhpennis Meigen, has been found in two of our eastern 
States, New York and Michigan, The only other records for 
eastern North America are northern Maine and Ottawa, Canada. 

In addition, the first known males and larvae of A, walkeri 
Theobald have been discovered. These were obtained in the 
same locality where the first examples of this species to be 



found in New York were taken and recorded by the writers 
in 1921. 

The discovery of these forms in New York increases the 
known Anopheline fauna for this State from three to five 
species. In a consideration of these new records it seems 
advisable to prepare a brief account covering all five of our 
species. As no additional species of this genus are known to 
occur in the States east of the Mississippi and north of the 
Ohio River, the North Atlantic States and Canada, the present 
paper may be considered as applicable for this entire region. 
The closely allied subgenus, Coelodiazesis, occurs in New Jersey 
and, as it may yet prove to belong to the New York State 
fauna, is also included. 

Unlike the other Culicid genera the species of Anopheles are 
very difficult to identify in the larval stages. No satisfactory 
characters have yet been used to separate our most common 
species A, quadrimaculatus Say and punctipennis Say. Howard, 
Dyar and Knab (1917) place them together in their key on 
the basis that both possess six pairs of dorsal palmate tufts. 
From an examination of many specimens of punctipennis we 
became convinced that there were only five pairs of these 
palmate tufts in this species. This agrees with the figure given 
by Howard, Dyar and Knab, though in the description of the 
larva it is again stated that six are present. In correspondence 
with Dr. Dyar he informs us that he likewise believes that 
only five pairs are present, the figure in the monograph being 
correct, Headlee (1921) ignores these palmate tufts and at- 
tempts to separate quadrimaculatus and punctipennis on the 
basis of mandibular characters. To the writers these characters 
seem too difficult to be of convenient use, especially when the 
more obvious character to be found in the number of dorsal 
palmate tufts is available.

Anopheles maculipennis Meig. has, until recently, been re- 
garded as an old world species. Edwards (1921) after an 
examination of both larvae and adults considers A. occidentalis 
D. & K. as identical with the European form. 

The distribution of this species is given by Howard, Dyar & 
Knab as “Western United States from southern California to 
Alaska, eastward through Canada to northern Maine.” The 
only records for eastern North America are Ottawa, Ontario, 
and Weld and Norcross, Maine. During the past summer a 
long series of this species was reared from larvae obtained 
along the marshy borders of Bessy Creek, a small stream dis- 
charging into Douglas Lake, Michigan. Here the larvae were 
associated with A. punctipennis, but the latter were present in 
very much smaller numbers. All about Douglas Lake the 
dominant Anophelinc was A. maculipennis, though A. puncti- 
pennis was captured or reared at intervals during the summer. 
Not a single specimen of A. quadrimaculatus was secured, 
although a large number of rearings were made and adults of 
this genus captured in the open. 

During a camping trip in the Adirondacks in the latter part 
of August, one male and seven females were captured on the 
walls of one of the permanent shelters at Racquette River, close 
to Buttermilk Falls, in Franklin County. This species proved 
annoying at this place. A single female was taken later 
(August 31) at Raybrook in Essex County. This locality is 
about 40 miles distant from Buttermilk Falls. 

A small collection of Anophelines from the University of 
Minnesota contains four specimens from Basswood Lake, Lake 
County, Minnesota, near the Canadian border, and two speci- 
mens from St. Anthony Park, Minneapolis. These records 
greatly extend the known distribution of this species for North 

In the table given for the larvae this species keys out with 
punctipennis. We separate them on the number of spines, both 
long and short, of the lateral plate of the eighth abdominal 
segment. The number of these spines, though somewhat 



variable, seems to offer the best available character for sepa- 
rating these species in the larval stages. Other characters, 
though somewhat variable, which may aid in the distinguishing 
of these two species are the two distinct transverse dark bands 
on the head of mactiUpcnnis and the outer humeral plumose hair 
which is longer and larger than the other two. In punctipennis 
the transverse bands of the head are indistinct or lacking and 
the outer humeral plumose hair is nearly uniform in size with 
the inner two. 

Anopheles walkeri Theobald. 

This is considered a rare North American species, the males 
and the larvae having been hitherto unrecorded. The first New 
York record was reported by the writers in 1921. Only females 
were taken at that time. During July, 1922, a large series of 
females (over 100), three males, two larvae and a pupa were 
taken at the same place ( North Fair Haven, New York). From 
the pupa a male later emerged. At this time this was one of 
the most abundant s[)ecies there, rivaling Mansonia perturbans 
in numbers and eagerness for blood. The females continued 
their attacks long after dusk. Again in September the place 
was visited and al>out twenty females and nine larvae were 
collected. A distinctive feature of this region is a slow, winding 
stream, Sterling Creek, whicii is ])or(lercd by broad stretches of 
cattail marshes. The lar\ae were found very sparingly through- 
out the marshes in small collections of water. 

Larva, Stage IV. — Head quadrate, about as wide as long, 
slightly bulging at the sides, frontal portion before insertion of 
antennae conically produced ; two long approximate setae on 
front margin ; a pair of dendriform branching hairs on the 
clypeal margin dorsad of the mouth brushes; a pair of incon- 
s])icuous hair tufts caudad of these; dorsal head hairs six, 
single but numerously branched, in a curved line between an- 
tennae, a plumose hair of larger size at base of antennae ; four 
smaller plumose hairs in a line l)etween the eyes. Antennae 
subcylindrical, slightly tapered, strongly spined on inner side, 
shorter and fewer spines on outer, a single branched hair at 



basal two fifths ; apically two long dentate, articulated processes, 
two short spines and a single branched hair. Mental plate 
elongate, triangular, with a central, broad, slightly indented 
tooth and six lateral teeth; first and second teeth equal, third 
and fourth pointed, fifth and sixth minute and distant. Hypo- 
pharyx (mental plate of Howard, Dyar and Knab) slightly 
elongate triangular with a prominent central tooth and four 
lateral, first lateral being small, second and third large and 
equal, fourth small. Mandible long, finely quadrangular, convex 
without ; ten branched hairs in a line forming a fringe directed 
forward, two prominent branched ones near them ; two pairs of 
flat appendages arising near tip, the first one simple, the second 
thinly feathered, the third and fourth heavily feathered; an 
outer row of cilia; terminal dentition of nine teeth, the first 
large, broad, obtuse, the second small obtuse lying in a deep 
depression between first and third, third longer than first, bear- 
ing on its inner side the small fourth and fifth teeth, the others 
small ; two filaments above and three within ; a square heavily 
dentate process below, the teeth rather long; a thick process at 
end of dentition, one at base, between these a row of setae, the 
central one the longest. Maxilla rectangular, the palpus at- 
tached by a narrow constriction ; numerous long setae and short 
spines on inner aspect ; palpus with rounded projecting base, a 
dendritic tuft within, four terminal digits and two flattened 
appendages. Thorax rounded quadrate, about as long as wide , 
hairs short, consisting of branched hairs, single hairs and tufts. 
Abdomen stout, anterior segments shorter; long feathered lat- 
eral hairs on first three segments, double on first and second, 
single on third ; posterior hairs smaller, three to seven branches ; 
a dorsal series of six pairs of fan-shaped tufts on second to 
seventh segments, the first slightly smaller. Air-tube sessile, 
subquadrate, roundedly angled posteriorly. Lateral plates of 
eighth segment broadly triangular with apex cephalad, armed 
on caudal margin with a series of long and short spines varying 
in number from 20-25 (7-9 long). Anal segment about as long 
as wide, with a small dorsal plate; dorsal brush a long and a 



short tuft on each side; a single long lateral hair near lower 
margin of plate ; ventral brush well developed, of long branched 
tufts. Anal gills moderate, longer than segment. 

The larva of this species is closely allied to that of A, quad- 
rimaculatus Say, having in common with that form six pairs of 
palmate dorsal tufts. A, quadrimaculatus differs in the follow- 
ing characters : The head is considerably longer than wide, the 
mandible has a terminal dentHion of eleven teeth and six 
branched hairs in a transverse row, directed outward; the 
feathering of the flat appendages differs as shown in the figure. 

Female . — For detailed description see Howard, Dyar and 
Knab (191?). 

Male , — The male has previously been unknown. The writers 
secured four specimens, one of which was reared from the pupa. 

Palpi nearly as long as prol)oscis, the last two joints swollen 
and club-shaped, with many long yellowish-brown silky hairs; 
vestiture black, the apex of second segment ringed with dull 
white. Antennae plumose; last two joints long and slender, 
rugose, pilose, black, the others short, pale, with narrow brown 
basal rings ; hairs of whorls long, dense, brownish. Occiput 
with a median groove clothed with erect black scales inter- 
mixed with longish black hairs, a tuft of brownish yellow hairs 
projecting forward between the eyes ; a row of black bristles 
along margins of eyes.

tles. Mesonotum narrow, elongate, brownish gray, slightly 
pruinose in two narrow strij^es on anterior half ; vestiture of 
short, sparse, golden brown hair- like scales, slightly denser

brownish-gray, slightly rugose ; vestiture of numerous long dark 



Wings hyaline, indistinct spots of black scales at origin of 
second vein, cross-veins, and at base of first forked cell. No 
spot at base of second forked cell. Halteres yellow.

apices of tibiae white. Claw formula, 2-0. O-O-O.O. 

Length : Body about 5.5 mm. ; wing 5 mm. 

Genitalia , — Side pieces longer than wide, somewhat conical. 
A well developed internal spine about one-third down tte side- 
piece. Basal lobes distinct with two prominent spines. Inner 
slightly shorter than outer, stout recurved, blunt at tip. Outer 
tapering to a point. Both arise from strongly chitinized pro- 
tuberances, that at the base of the inner spine being the larger. 

Claspette distinctly bilobed. Inner lobe bears a long, sharp- 
pointed spine at apex. Slightly mesad of this is a second 
shorter, pointed spine. The inner margin of the lobe bears 
numerous small hairs. Ventral lobe bears at apex two large, 
broad, club-shaped processes which are united at their bases. 

Aedoeagus narrow, elongate, strongly chitinized with four 
unequal rod-like leaflets at the tip. 

Ninth segment apparently well developed. Ventral processes 
loi^ and prominent. Anal lobe reaches well beyond aedoeagus, 
somewhat chitinized and bearing numerous small hairs ; divided 
at the tip. 

Distribution. In addition to the above record and those given 
by Dyar (Proc. U. S. Nat. Mus. 62, 106, 1922; and Trans. 
Roy. Can. Inst. Toronto, 1.3, 120, 1921) we can add a single 
record from Grand Rapids, Minnesota (August, 1896).

until the true male of galoa is known, no change is suggested. 

Wyeomyia (Heliconiamyia) galoa Dyar & Knab. 

The single female type. The wing-scales are broad; pro- 
thoracic lobes dark blue; vertex with diffuse median bronzy 
area ; tarsi dark, the last hind tarsal only whitish beneath. Bred 
from flower-bracts of Heliconia, Guatemala (Schwarz & 

Wyeomia (Heliconiamyia) chalcocephala Dyar & Knab. 

The female type and three males. The wing-scales are broad ; 
prothoracic lobes brown, of the color of the mesonotum ; vertex 
narrowly and faintly bronzy centrally; mid tarsi with third to 
fifth joints continuously white below, hind tarsi whitish below, 
especially on the last joint, but the color is not bright; in the 
male, the mid and hind legs are continuously white below. 
Bred from flower-bracts of Hchconta in Guatemala, with the 
preceding (Schwarz & Barber). 

Wyeomyia (Menolepis) culebrac, new species 
Clypeus nude ; metanotum with flat white scales. Prothoracic 
lobes and mesonotum with dark scales; abdomen dark above, 
white below, the colors separated on the sides in a straight line. 
Legs bronzy black, femora pale beneath, tarsi without markings. 
Wing-scales narrow. Head dark scaled behind, the eyes appar- 
ently without any white border. Prothoracic lobes with a few 
white scales at tip.

Dendromyia chrysomus Dyar, Ins. Ins. Mens, vii, 125, 1919. 

In the monograph, it proves that the males of IV , chrysomus 
served us as the supposed males of three species, chrysomus, 
philophone and mataca. I corrected the matter in regard to 
mataea (Ins. Ins. Mens., vii, 125, 1919), leaving that species 
without a known male, and now, unfortunately, must do the 
same for philophone. The type of philophone is a female, taken 
by Busck in Tabernilla, in the old days before the canal was 
built and this region flooded. The prothoracic lobes are dis- 
tinctly light blue, not coppery; but in other characters — long 
proboscis, white spot on vertex and white on mid legs only — the 
species is like chrysomus. There is no male before me. Busck’s 
rearings from Tabernilla (Nos. 177 and 191) are both of the 
coppery-lobed chrysomus. The type of philophone therefore 
stands alone, although I have series from Porto Bello (Jen- 
nings) and Taboga Island (Rusck and Zetek) which seem to 
agree. It is possible that this species can no longer be found 
in the Canal Zone, but will have to be sought in more richly 
tropical and undisturbed regions. It is possible that the species 
is dimorphic in coloration, and that melanopus Dyar is the 
male of it. I think that this will prove to be the case ; but until 
breeding of l)oth sexes has l)een had from the same culture, it 
would be premature to make a definite reference to the 
synonymy. In any, both philophone and mataea will fall 
to the earlier described celaenocephala D. & K., the prothoracic 
lobes of the type being rubbed, but otherwise agreeing |)erfectly. 
A corrected drawing of the clasper of chrysomus is added 
(PI. V, fig. 1).

I'hese names were originally proposed for supposed differ- 
ences in the white markings behind the eyes and at tips of 
prothoracic lobes ; but the diflferences are partly imaginary and 
partly due to the condition of tnc specimens and to variation, 
l^ater I thought to recognize four species on the shape of the 
male clasper ; but I am now convinced that the differences are 
illusory. The “core arm*’ of the clasper, while normally re- 
curved and crossing the middle of the disk, may be folded back 
along the stem or lie wholly detached, thus giving rise to the 
different appearances. I'he specimen which I assigned to 
labesba is evidently a broken one. 

Lutzia brasiliae, new species. 

Wing markings as in bigotii Bellardi of Mexico, as noted in 
the monograph (Howard. D\ar & Knab, Mosq. No. & Cent. 
Am. & W. I., iii, 410, 10151. The male hypopygium, however, 
shows distinct characters. The mesosome (PI. V, fig. 2) is 
smooth, without any teeth, being only slightly lamellate on the 
margin, w^hile the single terminal tooth is large and directed 
laterally. In bigotii (PI. W fig. I) there are many rounded 
denticles on the prehensile edge, and the terminal tooth is more 
pointed and smaller. The three rods on the side piece (PI. V, 
fig. are supplemented by several .setae on the basal side, as 
in bigotii Bell. In comparison with allostigma H., D. & K., 
which intervenes geographically between the two other species, 
the structures are quite different, the mesosome (PI. V, fig. 5) 
having a long narrow tooth with .sharp denticles beyond the 
middle, while the rods of the side piece (PI. V, fig. fi) are 
without additional setae basally. 

Types, male and female, Sao Paulo, Brazil (Dr. A. Lutz). 

Culex (Choeroporpa) \gcymon, new specie«5. 

A small bronzy black mosquito; wing scales narrow, broadly 



linear on the forks of second vein; femora narrowly white 
beneath; abdomen with whitish basal segmental lateral spots; 
venter whitish at the bases of the segments; palpi short in the 
female, exceeding the proboscis by half the length of the last 
joint in the male ; scales on the occiput all rather xiarrow. 

Male hypopygium. Side piece shortly conical, about as wide 
as long, membranously produced at tip, bearing the clasper and 
lobe (PI. V, fig. 7). Clasper snout-shaped, greatly produced, 
with crest and seta at the bend, the spine subterminal, widened 
and appendiculate. Outer division of the lobe of side piece 
broadly conical, without limbs but forming elevated bases for 
the filaments, of which there are three, two with pointed tips, 
one with expanded tip and directed outwardly at the base of 
clasper; two smaller setae, near tip and base of the structure. 
Inner division columnar, stout and long, with two short strong 
filaments with bent expanded tips, one inserted basad of the 
other. Tenth sternites comb-shaped, with long stem and about 
fine teeth. Mesosomal plate with the third point subapical 
on the stem, stout and curved; outer arm a long horn; inner 
arm broadly expanded, forming a long curved margin, sharply 
serrate with numerous teeth. Ninth tergites elongate, the tip 
recurved, and bearing many long dark hairs (PI. V, fig. 8), 
this tip appressed to the base of the side piece, like a basal lobe, 
so firmly that it comes off with the side piece when that is 
detached in mounting (PI. V, fig. 7). Many long dark hairs 
on the eighth segment, similar to those on the tips of the ninth 

Types, a male and four females, bred from larvae “in slowly 
running spring, full of leaves and small fish. A pretty, dark, 
black-marked species with small pupa.” Tabernilla, Canal Zone, 
Panama, May 2, 1907 (A. Busck). 

This well-marked and peculiar species was originally deter- 
mined as '*Culex ele^^ator*' and is recorded under that name in 
the monograph (vol. iii, p. 417, 1915). Blnfator was described 
from larvae only ; but adults, apparently from the type locality, 
are in the collection, on the basis of which I defined the species 


(Ins. Ins. Mens,, vi, 10(5, 19J8, and viii, 60, 1920). In the 
monograph records, the Rio Aranjuez, Costa Rica, specimens 
are the types of educator: Port Limon, the accepted types of 
elei^ator; Tabemilla, Canal Zone, May 2, are egcymon, de- 
scribed above ; May 13 of the same entry are iolambdis Dyar, 
while the record from Caldera Island, Panama, appears to be 
correct, elevator D. & K.

by us. Corrections are as follows :

Doctor and Mrs. Bonne referred Culex chrysonotum to the 
synonymy of M elanocomon thcobaldi Lutz ( Ins. Ins. Mens., 
ix, 20, 1921); but I think that this action was not carefully 
considered. It implies that chrysonotum from Panama is spe- 
cifically identical with thcobaldi of Brazil, and this was hot 
established by the compari.son of males. 1 am assuming that 
some at of the small Choeroporpa have a distribution as 
wide as this, hut the recent work of Gordon and Evans 
shows that the species which thev identify as chrysothorax 
Newstead & Thomas has different structures, apparently of 



specific value. I therefore suggest the following arrangement 
of names:

Culex (Culex) lepostenis, new species. 

Male hypopygiuni essentially as in stcnolcpis D. & K. ; but 
the color of the adult differs so much as to require another 
name. In stcnolcpis the tarsi are broadly ringed with white at 
both ends of the joints, and the proboscis of the male has a 
broad white ring. In lepostenis, the tarsi are very narrowly 
white-ringed at the bases of the joints only, and the proboscis 
of the male is entirely black. 

Type, male, paratypes, two males and two females, Cascajal 
River, Panama, May 30, 1908 (A. H. Jennings), originally 
determined by the late Frederick Knab as rejector D. & K., 
but without microscopic examination. The coloration is essen- 
tially as in rejector, and both species live in the water in the 
leaf -bases of arboreal Bromeliaceae. 



From the description, evidently similar to Melanoconion 
fascwlatus Lutz (Imp. Med., Feb. JO, 1905); but the Lutz 
species is evidently a Miaoculcx and not a Culex, having the 
appressed scales of the forked veins obovate. It may be an 
earlier name for rejector; but Brazilian males need to be 

Culex (Microculex) imitator Theobald. 

All the records in the monograph ( Howard, Dyar & Knab, 
Mosq. No. & Cent. Am. & W'. 1., iii, 434, 1915) for this 
species from Panama refer to jenningsi D. & K. Jenningsi is 
the Panama representative of imitator of Trinidad and the 
Guianas, and the two do not occur together. There are diifer- 
ences in the male hypopygium. which, while not great, are 
doubtless specific. 

Uranotaenia coatzacoalcos Dyar & Knab.

xiv, 186, 1906 

(yanotaema basalu Howard Dyar Knab, Mosq No. &’ Cent 
Am. & W I., iv, 917, 1917. 

These two descriptions can be compared only in the larvae. 
In coatzacoalcos^ we found the “upper lateral head hair” long 
and single, but short and double in basalis. I am of the opinion 
that we confused the homology of these hairs. The coatza- 
coalcos larvae are in Stage 111, the basalis larva in Stage IV. 
Between these two stages, tlic elongation of the head occurs. 
Stage 111 head is not much longer than wide, if any. The 
thickened clypeal hairs are long an<l spine-like ; there is a single 
hair at the margin of the eye-scar alK>ve the middle, and a 
multiple tuft {losteriorly. near the angle of the head. In Stage 
IV the head is much longer than wide. The thickened clypeal 
hairs are shorter and thicker ; there is a single hair near the 
center of the eye-scar, and a multiple tuft on the margin of the 
eye-scar above the middle. I do not detect any other hairs in 
this region in either mount. It seems probable that the elonga- 
ti(»n of the head has drawn the single hair from the margin 
across to the center of the eve-senr. and the tuft from the 


angle of the head down to the eye-margin. If this be so, then 
the two hairs which we compared were not homologous, and 
the supposed specific difference between the larvae disappears. 

This species appears to be confined to Mexico and Cmtral 
America, no specimens having appeared from Panama as yet. 
Dr. Alfaro was able to send me a nice series of the species 
from Costa Rica.

Anopheles neivai Howard, Dyar & Knab, Mosq. No. & Cent Am. 
& W. I., iv, 986, 3917. 

I cannot determine more than one species of Anopheles in 
Bromeliaceae, with slight local variation. The whitish shading 
on the third vein is distinct in the southernmost form (crusii), 
in which the tip of the fifth hind tarsal is white. In Trinidad, 
the white persists on the third vein, though fainter, while the 
fifth hind tarsal is dark {bellator). Coming westward, we 
find hylephilus, descrilied from Venezuela, Ecuador and 
Panama. Eliminating the latter locality, we find the third vein 
dark, or with only the faintest trace of white, the costa! spots 
of the wing of good size, the outer three reaching the costal 
edge. In Panama, the coloration is the same, except that the 
wing-spots tend to be small, often breaking away from the 
costal edge. In the type of neivai, the two basal spots have so 
broken away ; but in another, only the second spot has done so, 
while in a third the outer spot is missing. There is no constancy 
in the character, and I am inclined to refer all the Panama 
material to neivai, including those formerly listed tmder 
hylephilus, among which is one of the types of hylephilus. The 
specimens from Costa Rica mentioned in the monograph (vol. 
iv, p. 988) are in too poor condition to make out the characters, 
while those from Mexico were not bred to the adult state.

The new species of Trichocera described in this paper were 
included in collections of crane-flies received from Mr. W. 
George Howes, to whom my sincere thanks are extended for 
the privil^e of retaining the types. The family name 
Anisopodidae is used instead of Rhyphidae, the genus Anisopus 
Meigen (1804) having undoubted priority over the genus 
Rhyphus Latreille (1805). This usage of the family name has 
been adopted by Knab, Edwards and other students. 

Genus Trichocera Meigen 
Trichocera howesi, new species. 

Mde. — Length about 2.(! mm. ; wing 3.3-3.4 mm. 

Female. — Length about 2.8 mm. ; wing 3.5 mm.

verse, near midlength of cell rst w about one-half the 
petiole of cell A/, ; m-cu about two-thirds the basal deflection of 
Cm,. In the left wing of the type, vein just before its tip 
bends caudad and fuses with R„ completely closing cell R^. 

Male hypopygium with the pleural appendage on the mesal 
face at about one-third its length produced into a slender, 
subacute, glabrous lol)e ; mesal face of the appendage distad of

same general nature as in T. maori, forming large cushions, 
the armature reduced to abundant microscopic spinules.

This very interesting crane-fly is named in honor of the 
collector, Mr. W. George Jlowes, to whom I am greatly in- 
debted for many kind favors. 

Trichocera lyrifera, new species.

mesal face at the base but not produced into a lobe, the entire 
mesal surface of the appendage provided with abundant, erect 
setae. Gonapophyses taken together lyriform, each a slender, 
strongly curved rod. Above the genitalia lies a microscopic, 
shagreened structure, deeply emarginate caudally, each lateral 
lobe thus formed produced into a needle-like point.

There are extant two comprehensive tables of genera in this 
family: one by Speiser in Wiener Ent. Zeitung., xviii, 1899, 
201 ; the other by Massonat, Annales Univ. Lyon, 1909, 234. 
Among several partial tables may be noted one for eight South 
American genera by Lutz, Neiva and Costa Lima, in Mem. 
Inst. Oswaldo Cruz, vii, 1915, 170. I have thought it worth 
while to prepare a new table, as none of these includes all 
genera now known. In this 1 have endeavored to arrange the 
characters so as to bring the less specialized forms at the begin- 
ning; inasmuch as specialization among these flies is in the 
direction of reduction, the mure generalized forms are those 
with functional wings with comparatively complete venation, 
while the sheep-tick represents the last term of the series. 
Lipoptena is an isolated group, as shown by the venation, which 
IS figured by Ferris and Cole, Parasitology, xiv, 184.

I'he status of Pseudolfersia is as follows: Originally in- 
cluded in Olfersia (as Frronia, preoccupied) were both spinifera 
and americana. When Coquillett established Pseudolfersia 
(Canad. Ent., xxxi, Nov. 15, 1899) he designated maculata, 
new species, as type, which agrees with spinifera in characters, 
as distinguished in the above table. He evidently intended to 
leave americana in Olfersia as tyi)e. But unfortunately Speiser’s 
table of genera contained the designation of spinifera as type 
of Olfersia, and came out July ;i1, 1899, almost four months 
ahead of Coquillett. Thus it results that Pseudolfersia is merely 
a synonym of Olfersia, and the group represented by americana 
(several species) has up to the present no generic name. The 
generic characters exist as seen by Coquillett, and if he had 
known of Sj)eiser’s designation in time he could easily have 
named americana as type instead of maculata. My new genus 
Ornithoponus, type americana, will fill the existing vacancy. 

The genus Ornitheza is not known from North America, but 
includes Ornithomyia butalis Coq., from the Commander 
Islands. I erroneously sup{)Osed these islands to be North 
American when preparing my Catalogue, but they are near the 
Asiatic coast and should be relegated to the palaearctic, 

Rondani described Ornithophila vagans from a single fly 
found in Italy, wandering on the limb of a tree. His type seems 
to be lost, and the species, the only one of the genus, has not 
been rediscovered. In the National Museum collection is a 
specimen from St. Helena, Bolivia, collected by Dr. Wm. M. 
Mann on the bird called huichi, which runs to this genus in 
the table. 

Specimens of Lipoptena are not rare, and good series are 
sometimes obtained from deer, which they infest. Such series, 



however, have almost invariably lost the wings, only stumps 
remaining. On July 4, 1!)17, near the summit of Mount Lowe, 
Southern California, I collected a winged specimen which I 
noticed hovering in the air in a shady spot. After it was in 
the cyanide tottle it rose on the wing and hovered in the middle 
of the bottle for an instant, a feat which I have never seen 
l)crformed by any other fly. 

(Jrnithoica conflucns Say is a widespread and well-known 
species, although not abundant in collections. It occurs on 
many hosts. Specimens in the National Museum are from 
Santiago de Cuba, without host; Hotchkiss, Colo., “on Hawk 
and Owl" (T. 11. Cowen, through C. F. Baker) ; Ontario, Cal., 
on Cypsdus mexicanus ( Snodgrass) ; Philippine Ids., on 
IlulcyoH { Philippine Bureau of Science) ; and seven specimens 
from Tutuila, Samoa, on Halcyon tutuilae (Lieut. E. C. Reed, 
U. S. N.). Comparing this distribution with Austen’s notes 
(Ann. and Mag. Nat. Hist, 1903, <Jt)3), it seems safe to assume 
the synonymy of Kond.'ini's bct'carinia, de.scribed from Amboina. 
Schiner’s Ornilhomyia pusilla (Novara, 374; from Tahiti, on 
Halcyon rrmratuiii, is also a synonym. (Juite recently the 
species has again been redescribed by Ferris and Cole as 
Ornithoica promiscuo ( Para.sitology, xiv, 203). Their speci- 
mens were from several hosts in California. 

Say called the species conflucnta, forgetting for the moment 
that the ],atin participles have the same form for all genders. 
Wiedemann corrected the name to conflucns, adding in a foot- 
note that Say’s form was a slip of the pen or a misprint. 1 
think we may go so far as to give a specific name the proper 
ending for gender without raising any question of rules. 

Of the 24 genera nt)w known, representatives of 18 are in 
the National Museum; the ones lacking are Pseudornithomyia, 
Icosta, Uchestypus, Stenoptcryx, M yiophthiria, and Brachy- 




{Dipiera, Syrphidae ) 


A wonderfully striking species of Microdon was collected 
by Dr. W. M. Mann, while with the Mulford Expedition in 
Bolivia, 1921. The very unusual type of wing coloration singles 
out this species immediately, and as the writer is unable to find 
a description to fit the form, it is here described as new. 

Microdon manni, new species. 

Female . — Among the larger species, black with a large con- 
spicuous preapical white spot on wings. Scutellum spined. 
Head broader than high, obtusely oval, face somewhat produced 
downward; face broad, parallel sided, eyes but little converging 
toward apex, the front being about two-thirds width of face; 
ocelli closely grouped and placed but little behind center of 
front; antennae elongate, cylindrical, first joint nearly as long 
as width of front measured across base of antennae, second 
joint small, but little longer than broad ; third joint somewhat 
longer than combined length of first two; arista a little shorter 
than first joint ; face with large dark brown spot which is bor- 
dered by a luteous V shaped marking; cheeks shining black. 
Mosonotum black, posterior margin of scutellum luteous, which 
color includes the two well separated, medium sized spines. 
Legs black, apices of femora and bases of tibiae brownish ; fore 
and middle tarsi a little shorter than length of their tibiae ; hind 
tarsi longer than hind tibiae. Basal two-thirds of wings pure 
black, a broad white spot extends from anterior to posterior 
margins, the parts of the veins covered by the spot yellowish ; 
a distinctly smoky spot at apex of wing. Squamae and halteres 

Length Ifi mm., wing 13 mm. 

One female, Ivon, Rio Beni, Bolivia ; W. M. Mann, collector. 

The coloration of M. manni makes it unique among our 
American Microdons. The species which most closely approach 

^Result*? of thr Mulford RioloKical Exploration — Kntomo]of?y. 



it in coloration are to be found in the small group, M. mirabilis 
Will., bertonii Bezzi, iheringi Bezzi, recently worked up by 
Bezzi (Wien Ent. Zeit., 29, 319, 1910). However, the light 
preapical spot is represented by a narrow stripe extending across 
the wing. The scutellum in this group is unarmed. 

Microdon bertonii Bezzi. 

This species belongs to the group just mentioned. The 
specimens upon which Bezzi based his description lacked their 
antennae and as the National Collection now contains a pair 
of this species (det. by F. Knab) which have antennae, the 
writer is able to describe them. Antennae black throughout; 
first joint cylindrical, about two-thirds the width of front meas- 
ured across antennal base ; .second joint small, broader than 
long; third joint in female broad, tapering at apex, more slender 
in the male, and al)OUt as long as first joint ; arista as long as 
first joint. 


{Dxpte'ra, Cuhcidae) 


The species of Gocldia { Lesticocampa) are predacious in the 
larval state, as far as known, and are addicted to the Sabethids 
or Culicids of certain plants. Consequently there exists a 
species for each plant, or rather for each group of species with 
a different habitat, siticc some of the victimized Sabethids 
inhabit water in dead tissues. 1'he table of the male genitalia 
given in the monograph (Howard, Dyar & Knab, Mosq. No. & 
Cent, Am. & W. L, iii, l(i3, 1915) is unusually perfunctory and 
inexact. The following will better separate the males at present 
known. Of the species mentioned by Bonne-Wepster & Bonne 
(Ins. Itis. Mens., x, 38, , 7'onplesscm, lineata, schedocyclia, 

trichopus, frontosa, and t>ara}icnsis are unknown to me in the 
male sex. Of the four last named, the male is undiscovered.

* The International Commission has ruled that m case of misidentiheations. th** 
t>i)e of a genus is to be taken as the species named by an author, and not what 
he may actually have had before him. Therefore, the type of Isostomyia Coquil- 
lett is Acdcs perturhans Willi.ston, as stated in the monograph (Howard, J>yar & 

Knab, Mosq. No. & Cent. Am. & W. I., iii 187, 1915). Ihe use by me of the 
name as a subgenus of Culcx (Ins. Ins. Mens., vi, 92 and 102, 1918) is not per 
missible. For Isostomyia I>yar (not Coquillett), the name Aedinus Lutz may be 
tentatively used Gordon and Evans ligure well the structures of their Culex 
originator (Ann. Trop. Med & Par., xvi, 324, 1922), which species is pre- 
sumably the same as Aedinus amaconensis Lutz, described from the same gen- 
eral region. Theie may. of course, be more than one Cules with short palpi in 
the male in the Amazon region; but until some differences have been pointed 
out between originator and amasonensts, thej may be assumed to be the same. 
The structure of the clasper of originator agrees with my definition of Isostomyia 
(Ins. Ins. Mens, vi, 92. 1918).

LesHcocampa dicellaphora Howard, Dyar & Knab, Mosq. No. & 
Cent. Am. & W. L, iii, 166, 1915. 

Male hypopygium. Side piece conical, about two-and-a-half 
times as long as wide, constricted at base ; a group of about 20 
closely set large setae from conspicuous tubercles on the inner 
basal angle. Clasper as long as the side-piece, with long in- 
serted terminal spine. Tenth stemites rather narrow, chitinized 
on one margin, ending in two widely spaced, distinct teeth. 
Ninth tergites low, much wider than long, approximate, each 
with five or six moderately long stout setae, which are not flat- 
tened nor blade-like. Eighth segment strongly chitinized, but 
of nearly normal shape. This agrees with the characters given 
in the monograph (vol. iii, p. 107) except as to the description 
of the ninth tergites (basal appendages). These were obscure 
in the old mount, and are corrected from a new one. 

The larvae are predacious upon those of IVyeomyia 
(Decamyia) eloisa H., D. & K. and IV, (Hystatomyia) coe- 
nonus H., D. & K. in the flower-bracts of Calathea discolor. 
No additional material is at hand since Jennings’ rearings. 

Goeldia (Isostomyia) perturbans W'illiston.

This species is not before mt, but has been examined by 
Bonne- Wepster and Bonne (Ins. Ins. Mens., ix, 16, 1921). 
The larvae are predacious upon those of IVyeomyia 
(IVyeomyia) pertinans Williston, presumably in the leaf -bases 
of Bromeliaceae. The only known locality is the Island of St. 
Vincent, West Indies.

The male structures have been described by Dyar and Ludlow 
(The Military Surgeon, 1, lU. 1922). The life habits are 



unknown; but the suggestion is ventured that the larvae are 
predacious upon those of Wyeomyia (Prosopolepis) prolepidis 
D. & K., “in cup-like shells which enclose the blooms of the 
seed-palm, which remain on the tree midway up, and readily 
catch and hold water” (The Military Surgeon, xlviii, 678, 1921).

Lcsticocavipa culicivora Dyar & Knab. Journ. N Y. Ent Soc., 
XV, 207, 1907 

Lcsticocampa ulopus was said to have the palpi of the 
female as long as six joints of the antennae ; but reexamination 
of the type shows this to have been an error of observation. 
The palpi, measured from the tip of the clypeus, do not in the 
least exceed the length of four joints of the antennae. Lesti- 
cocampa culicivora was associated by the collector with “some 
unbred long- tubed larvae, probably a species of Culex^ in 
flower-bracts of Heliconia, No Culex has since been found to 
breed in this plant, and the record is probably an error. 

Male hypopygium. Side piece rather narrow, long and taper- 
ing ; a group of coarse setae at tip within, another larger group 
from contiguous tubercles on the outer aspect toward base, and 
three very long flattened ones within. Clasper very long and 
slender, swollen at base, else uniform, curved before tip, and 
ending in a .short, blunt inserted spine. Basal lobes low and 
rounded, with many coarse flattened setae. Tenth sternites 
moderately broad, strongly chitinized on one margin, with four 
stout terminal teeth and one or two very small ones. Ninth 
tergites with the chitinized portion about as broad as long, 
scarcely exj^anded outwardly, bearing five to seven stout setae, 
which are flattened, blade-shaped, with slender tips. Eighth 
segment chitinized, but wider than long and normally shaped. 

The larvae feed tipon those of Wyeomyia {Decamyia) 
pseudopecte^i D. & K. and W. (D.) ofiidus D. & K. in the 
flower-cups of .several species of Heliconia. Our localities for 



the Goeldia include Guatemala, Nicaragua and Panama. The 
victimized species of IVyeomyia and the host plant have a wider 
distribution, along the north coast of South America to 
Trinidad. It is probable that Goeldia longipes has a similar 
distribution. The species is also predacious upon IVyeomyia 
{Calladimyia) melanocephala D. & K. in “elephant’s ear” 
{Calladium). Careful examinations reveal no differences in 
coloration or structure in the adults from the two plants. 
Calladium rearings are at hand from L. H. Dunn and J. B. 
Shropshire in the Canal Zone. Panama. 

Goeldia (Goeldia) lunata Theobald. 

H'ycomyia (unata Theobald. Mon. Culic., ii. 279, 190:^. 

Described from females from Rio de Janeiro, Brazil. 

Male hypopygium. Side piece rounded-conical, about twice 
as long as wide ; setae rather coarse, some broad and flattened, 
evenly distributed ; outer side scaled. Clasper longer than the 
side-piece, slender and curved, ending in a moderate blunt in- 
serted spine. Basal lobes low and rounded, with about six long 
flattened setae centrally and small ones on the sides. Tenth 
sternites long, narrow, chitinized on one margin, with four 
terminal closely set teeth. Ninth tergites wider than long, 
approximate, with six stout terminal setae, which are slightly 
flattened and blade-like with slender tips. Eighth segment 
more strongly chitinized than the seventh, but only slightly so. 

The larvae feed on those of Culex (Microculex) imitator 
Theob. in Bromeliaceae growing on trees (Peryassu, Os Culid. 
do Brazil, table insert at page 32G, 1908). 

Bonne- Wepster and Bonne describe the male hypopygium 
of this species (Ins. Ins. Mens., ix, 12, 1921), and remark 
that they find no differences from the structures of rapax D. & 
K. The differences are slight, as shown in the table, but I think 
they are of specific value.

very narrow, one margin chitinized. ending in two approximate 
teeth. Ninth tergites large, quadrate, approximate, with seven 
terminal stout flattened setae, which are not much longer than 
the tergites themselves, but flattened and blade-like, with slen-

Descried from Nicaragua and Panama. Additional material 
from Culebra and Empire in the Canal Zone (L. H. Dunn) 
and David, Panama (J. Zetek), is also all hand-caught, so that 
the life history is unknown. The adults differ from longipes 
not at all in coloration, but the hind legs are not ciliate. The 
genitalia are peculiar. 

Male hypopygium. Side piece long and slender, at least four 
times as long as wide, with fine and coarser setae within ; 
numerous coarse hairs without. Clasper unusually long and 
slender, with short blunt ovate terminal spine. Basal lobe 
broad and very low, with fine setae only. Tenth sternites 
large and very broad, one margin more chitinized than the 
other, having six terminal thorn-shaped oblique teeth. Ninth 
tergites slightly capitate, a little longer than broad, with six 
terminal, moderate flattened blade-shaped setae with slender 
tips. Eighth segment slightly chitinized, unmodified.

The description of the male structures given in the mono- 
graph has been supplemented by some details in the table. 

The larvae are predacious upon sjjecies of Culex {Micro- 
culex) found in the water in epiphitic Bromeliaceae. This 
comes from Trinidad, and the habits are evidently identical 
with those of Goeldia luuata Theob. of Brazil. Details of the 
male structures differ, apparently to a specific degree, although 
Bonne-Wepster and Bonne (Ins. Ins. Mens., ix, 12, 1921) 
considered them identical.

Bonne-Wepster and Bonne remark (Ins. Ins. Mens., ix, 15, 
1921) that the male genitalia are like those of longipalpis 
Theob. A specimen before me from Brazil differs, however, in 
the extremely short side pieces, which are scarcely longer than 
broad, and the distinctly long spine of the clasper. The eighth 
segment, too, is very strongly chitinized, and there are a number 
of other small differences. The species seems distinct. No 
data are at hand as to its life history.

Bonne-Wepster and Bonne remark (Ins. Itis. Mens.» ix, 15,

from those of rapax. The species is not before me. The life 
history is unknown. I have not been able to place the species 
in the table. 

Goeldia (Goeldia) lineata Peryassii. 

Runchotnyia lineata Peryassu, Os Culic. do Brazil, 266. 1908. 

This was described from a male, but the hypopygium was not 
fully described nor figured, and I possess no specimens of the 
form. With the tarsi all dark, as described, and a yellow line 
down the middle of the mesonotum, it should be an easily 
recognizable species. Nothing about the life history is given. 


{Diptera, Culicidae) 


This species was described from examples of both sexes 
collected in Winnipeg, Manitoba, by Frederick Knab in 1907. 
The original type series mentions 68 specimens found “along 
the banks of the Assiniboine River among the trees.” The 
assumption was that the species was connected with the river, 
and hence the name. There are 82 specimens in the collection 
now, collected by Knab at Winnipeg, but which are the original 
68 types is not indicated. Only two specimens bear type labels. 

In the monograph (Howard, Dyar & Knab, Mosq. No. & 
Cent. Am. & W. I., iv, 714, 1917), we give the additional 
localities, Aweme, Manitoba, and Saxeville, Wisconsin. The 
two specimens mentioned from Aweme taken by Mr. Norman 
Criddle are before me, but the one from Wisconsin I do not find. 

In the mosquitoes of the United States (Proc. U. S. Nat. 



Mus., Ixii, 80, 1922), I could not cite any United States records 
for the species, the specimen from Wisconsin having already 
disappeared then, or else it was a female and I was uncertain 
of the determination. In the same paper (p. 74), under 
flavescens Miill., I state that the two species are exactly alike 
in coloration, and liable to be confused. 

On account of the unsatisfactory state of knowledge, an 
effort was made to follow up this species. In the spring of 
1022 we went to Winnipeg, the type locality, early enough to 
find larvae, and later followed the species’ distribution into the 
United States. 

On becoming familiar with the species, there is no difficulty 
whatever in distinguishing it from flavescens (fletcheri). The 
difficulty was that in the flavescens series in the collection 
some riparius had been confused, so that my description of 
flavescens covers both species. To correct that description, the 
following changes are required in the paper : 

Page 74, lines 23 and 24, for '‘sometimes” read “not,” and 
for “diffused and with scattered scales,” read “sometimes show- 
ing black longitudinal markings.” 

Page 74, lines 33-36, delete the sentence “Liable to be ... . 

Among the specimens of ri partus confused under flavescens 
are the ones from Fort Snelling, Minnesota. 1'hat record should 
be deleted under flai*escens. 

The larvae were found in early spring pools, particularly the 
shallow but large flat pools under scrub oaks that grow in 
groups on the prairie in the moister undulations of the plain, in 
the suburbs of Winni|)eg The prairie in this region is not yet 
bare, though the forest is l^reaking up and the conifers are 
gone. Large and small rounded thickets with sharply defined 
edges, composed of aspen, scrub oak, sugar plum, etc., occur. 
The |X)ols have no connection whatsoever with the river, but 
are prairie pools. The Assiniboine here flows through a narrow 
gulch worn in the prairie, and forms no breeding-pools for 
mosquitoes whatever. Our conception of the species as ad- 



dieted to river banks was therefore wholly wrong. The adults 
do frequent cover as well as open prairie; that is, they do not 
shun cover as flavescens does. The river gulch looks like an 
inviting place to collect, and so Mr. Knab collected his series 

The larva has the head rounded, the antennae reaching about 
to the end of the mouth-brushes, slender, uniform, infuscated 
and coarsely spinose; a long spine at the tip. Head-hairs in 
twos, rarely one single. Body with the skin scarcely granular, 
nearly glabrous ; lateral hairs single beyond the second segment ; 
lateral comb of the eighth segment of seven or eight scales in 
an irregular row, each with very long central thorn, twice as 
long as the scale, with short fringing spines on the sides of the 
scale. Air lube about three times as long as wide, the pecten of 
about 12 teeth, followed by two, three, or four well detached 
ones, and the hair-tuft beyond, of three hairs and rather short, 
each tooth of the pecten with three to five branches at base. 
Anal segment with the plate coming near the ventral line, but 
not encircling, excavate posteriorly on the edge; brush with 
smaller tufts preceding toward base of the segment. 

In the i)enultimate stage (Stage III), the larva presents some 
clififerent characters. Head hairs 2-1 or 1-1 ; air-tube longer, 
al>out four times as long as wide; pecten in the same propor- 
tion, but the basal teeth smaller and more distant ; tuft 2-haired ; 
anal segment with the plate a dorsal saddle only, reaching about 
halfway down the sides ; lateral comb of the eighth segment of 
about 12 scales, each with central stout thorn, longer than the 
body of the scale, with slight lateral fringes. Skin glabrous. 

1 have shown (Ins. Ins. Mens., x, 72, 1922) that riparius 
is allied to the European maculatus Meigen by the structure 
of the male hypopygium; but the larvae of the two are very 
different, maculatus having the comb of the eighth segment 
with many scales and the pecten of the air-tube without detached 
teeth. The air- tube itself, however, has much the same pro- 
fX)rtion in the two. The larva is quite distinct from all the 
American forms. 



Leaving Winnipeg, we went to Warroad, Minnesota, a small 
hamlet on the south shore of the Lake of the Woods. The 
country here is forested, though there are some open spaces. 
The locality was especially favorable to riparius, much low land 
flooded by spring rains. The pools had just dried out, and the 
adults were starting on their migration flight. Under the trees, 
in leaves, in the grass along the moister parts of fields and 
ditches, they were present in numbers, both males and females 
in nearly equal proportion. Not flying much in the day, but 
on the alert and easily flushed up, only to settle on the grass or 
leaves again in a few seconds. Two hundred were taken along 
one lane in a quarter of a mile, without perceptibly affecting 

Later, in an opening of the woods, after sunset, a number 
of males were found perched in the top of a dead willow bush, 
and flew out when the bush was shaken. No true swarms were 
seen, although they undoubtedly occur, for by the time dispersal 
was effected and swarming would begin, the species had become 
rare in the original locality. 

Places visited later yielded the species in small numbers, 
biting by day or night, usually in open country. The adults, 
however, while at home on the prairie, also frequent the less 
shaded forest, as the following localities indicate.

This mosquito does not reach the Atlantic region, being lost 
in Ontario as the forest thickens eastward. It may, however, 
reach the Pacific coast, as there is a possibility that aloponotum 
Dyar from that region is the same thing. This I* have not been 
able as yet to establish on account of not having any males of 


(lyiptera, Culiridae) 


According to Dr. Wesenlierg-Lund's account of the habits 
of this species in Europe, the males do not swarm, but rest 
singly on the under side of the tips of fern-fronds, waiting 
for the female to approach. I had not seen the action of the 
males in America until last summer. At Bamesville, Minne- 
sota, there is a long and rather wide strip of land between the 
railroad tracks and private property which is low, and evidently 
held water early in spring. The area was dry at the lime of 
my visit (June 2, 1922) and grown up to coarse grass and low 
weeds. After dark on that day a number of males of A’edes 
flavescens (fletcheri Coq.) were seen, resting near the tips of 
grass-blades or the upper leaves of weeds. On being ap- 
proached, the male would fly away to another similar location. 



No matings were observed ; but there seems no doubt but that 
the males were behaving with us in the same manner as ob- 
served in Denmark. 

A full list of American records of this species, as shown in 
the collection of the U. S. National Museum, follows. The 
records of riparius which had been included by mistake have 
been weeded out. Compare my paper of the mosquitoes of the 
United States (Proc. U. S. Nat. Mus., Ixii, 74, 1922). The 
records given in the monograph (Howard, Dyar & Knab, Mosq.

The distribution is thus seen to be very wide in the north, 
reaching from Alaska to Hudson’s Bay, but more and more 
restricted to the central plains southward. The species probably 
occurs at least in South Dakota, but I have no material from 


(Diptera, Culicidae) 


I originally described this from females as a small form of 
A'edes hirsuteron Theobald (Itis. Ins. Mens., viii, 34, 1919), 
and later referred it as a synonym of aldrichi (Ins. Ins. Mens., 
ix, 79, 1921, and Proc. U. S. Nat. Mus., Ixii, 63, 1922). Males 
and larvae of the form were found at Warroad, Minnesota, 
adults appearing May 24 27, 1922. The larvae were in shaded 
shallow woods-pools, filled by rain, and entirely unconnected 
with flood'water. The country is low and flat ; the only stream, 
small and sluggish, empties at this point into the enormous 
Lake of the Woods, so that flood-water is uncommon. The 
form vinnipcgensis, therefore, is clearly not aldrichi, and is 
differentiated from hirsuteron in habit, by normally inhabiting 
spring-woods-pools. The larvae have the pecten of the air-tube 
not reaching beyond the middle of the tube, lateral tuft of the 
.sixth segment double, skin sparsely pilose, agreeing with 
hirsuteron and not with aldrichi. It may be considered a race 



of hirsuteron, small in size and living in early woods-pools 
instead of flood-pools of rivers. The position first assigned by 
me was the correct one. 

At Winnipeg Beach and Aweme, Manitoba, all the adults 
taken were small. At Warroad, Minnsota, however, a majority 
of the captured adults were large or of normal size. Again, 
in marshy land at Warroad, which had been largely overflowed, 
either by flood-water or rain, several specimens of Aedes 
trivittatus Coq. were bred together with vinnipegensis. This 
species is a typical flood-pool breeder, and in this pool the full- 
sized hirsuteron may have developed. Therefore it appears that 
Warroad is at the meeting-]x>int of normal hirsuteron and the 
small innnipegcnsis form. Farther south, at Thief River Falls, 
Minnesota, hirsuteron was found breeding in normal flood- 

Recently (Ins. Ins. Mens., x, 8;i, 1922) 1 discussed the 
relationship of hirsuteron and aestivalis to the European 
sticticus M eigen. I have now examined a mount of the male 
hypopygium of the European form, and find the filament of 
the claspette widely expanded, short, the expansion forming a 
right angle, with distinct striae or ridges from the base, which 
run into the expansion of the filament as far as the angle. In 
the American forms the filament is longer, the expansion 
rounded, and there are ik) striae or ridges at the base, the 
structure being uniform except appearing thicker along the 
edge away from the expansion. 

ft is therefore clear that hirsuteron Theobald is distinct from 
the European species. I am unable to demonstrate any differ- 
ences in aestivalis, which may be referred to the synonymy of 
hirsuteron. This will necessitate the following changes in my 
paper on North American mosquitoes (Proc. U. S. Nat. Mus.. 
Ixii, 1-119, 1922):

These species had escaped my utmost efforts in collection,

The excellent treatise by Dr. (iarry de N. Hough on this 
group, “S\nopsis of the Calliphorinac of the United States” 
(Zoological Bulletin, 11, 18^)1)), is the only compre- 

liensive work on our genera and species that has appeared. 
Nearly twenty-fi\e years have elapsed during which about a 
fift> per cent increase in the number of genera and species have 
been found in North America. Likewise additional characters 
ha\e come to light which more clearly classify the forms. As 
1 lough’s paper is now out of print a new synoj)sis of the group, 
cml)o(lying the new forms and characters, seems a timely matter. 
The present jiaj^er contains a great deal that is the work of 
Dr. J. M. Aldrich Three of the sjiecies of Stcntigomyia, re~ 

' orded below, besides almost the only known specimens of 
Calliphora (Cvvomvia) clongata Hough, were obtained through 
his collecting The discover} of the main generic character 
used in the key for ( ochUomyia should be credited to him, 
although Townsend erected the genus. Most of the characters 
of the male genitalia and the character of “stem vein ciliated,” 
here used by the writer, were jx^inted out to him by Aldrich. 
Most of the synonymy was obtained from Aldrich’s card index, 
and this is indicated in the proper places. Credit should also be 
acknowledged for his efforts, in conjunction with Villeneuve, 
in ascertaining the relation of the sjiecies of Steringomyia and 




Onesia to European forms. Much appreciation is due Dr. J. 
Villeneuve for making these necessary examinations and for 
his opinions. 

Mr. J. R. Malloch was the first to point out the character 
used for Lucilia, i. e., the hairy chitinized patch between the 
squama and post alar declivity; besides the hairy post alar 
declivity and the single convexity of the metanotum, two char- 
acters common to most Calliphoridae and their allies. 


The family Calliphoridae may be defined as follows : Cyclor- 
raphous flies with large squamae; hypopleural bristles present; 
sternopleurals arranged 2:1; plumose arista ; metanotum with 
a single convexity; tuft of hairs on post-alar declivity (except 
one or more species of ProtocalUphora ) ; a small patch of 
inconspicuous setae on metanotum below each squama; pros- 
temum (between fore coxae) pilose ; propleura entirely clothed 
with pile, besides having the usual bristles on the lower pro- 
pleura, i. e., the restricted area immediately above coxae; 
metallic light green to dark blue in color. 

The pilose prosternuni and upper propleura are here pro- 
posed for the first time, as far as the writer is aware, as the 
limiting family character for the group. 'I'he pilose prosternum 
appears to be common to all of the American flies which may 
properly be considered as belonging to the Calliphorid group, 
even the testaceous Mesembrina and allies. This character 
appears to segregate the Calliphoridae from all other American 
Muscoid Diptera except a few genera of Muscidae (sensu 
vero) which are eliminated by the absence of hyj)opleuraI bris- 
tles, and some of the more bristly Tachinidae which could not 
be confused because of their bare arista and hind coxae pilose 
on posterior side. Pollenia, as well as the Sarcophagidae, 
Dexiidae and most Tachinidae have the prosternum and upi)er 
propleura l)are. The Anthomyidae and some Muscidae also 
have these parts bare. Pollenia, because of its grayish, non- 
metallic coloration, sternopleurals arranged 1 :1 and unique 



parasitic habits (parasite of earthworms) is manifestly an 
unnatural element in the Calliphoridae,' all of which are of 
some metallic shade of blue or green and usually breed in either 
living or dead flesh of vertebrate animals. 

Two subfamilies and four tribes are present in our fauna. 
The Phorminae containing the tribes Chrysomyini, screw worm 
flies; and Phormini, in which some of the species have larvae 
parasitic on nestling birds. The Calliphorinae are also repre- 
sented by two tribes in North America, the Lucilini which 
frequently adopt the parasitic habits of the screw worm flies 
and are a great pest on sheep at times, and the Calliphorini or 
typical blue bottle flies. The genera of Calliphoridae which 
occur in North America appear to be restricted to the holarctic 
region. In South America the “blow-flies” are represented by 
the Mcscmbrina and allies (a group which Aldrich has recently 
revised), and the Lucilini and Sarconesini. A few species of 
Calliphorini are known to occur in the Neotropical region but 
material is not at hand and they have l)een left out of con- 
sideration in the present paper. They appear to be confined to 
high altitudes 

The genera previously unrecorded for America are Borr'cllus, 
poh.sil)!} uni(jue to the boreal region ; and Steringomyia and 
Oficsia, both well known European genera. The appearance 
of tlie latter genera in America is really a matter of note; we 
now have authentic records of four species of Steringomyia 
and two of Oticsia, all but one of Steringomyia being obtained 
only during the last five or six years. A number of the genera, 
or so-called genera, are monotypic for North America, and this 
fact, together with the revision giv^n for the Calliphorini. makes 
the present treatment complete for the Nearctic Calliphoridae 
except the species of Lucilia. 

Townsend has recently described a new species of Callipliora, 

^ Mclanodexia, Dexiidae, ai)pc.irs to have more in common with Pollcma than with 
other Uexnilae The heads of the two resemble each other closely and they agree 
otherwise, < ven to having the post alar declivity hairy (which is not the case 
in the true Dexiids) except for the absence of the small parch of halts below 
the squama in Melanodexia, 



texensis, based on five specimens from Texas. The specimens 
prove to be Cynomyia cadaverina Desv. His species, CaUiphora 
{Musca) rubrifrons, is none other than C. vomit oria. The 
character of red frons, whereby he distinguished the species, 
is peculiar only to somewhat teneral specimens. Likewise the 
species he described from Mexico and Costa Rica, Calliphora 
irasmna, is vomitoria, or, at best, it is merely a variety of 
vomitoria of the black beard form and otherwise distinguished 
by its darker wing bases. Townsend has erected the genus 
Cynomyiopsis, to contain Cynomyia cadaverina, Calliphora 
clongata and Steringomyia popoffam, an unnatural group for 
which we have no need and the name is here made a synonym 
of Cynomyia, Also there is no need for his genus Eucalliphora, 
described for Calliphora lati frons, on the basis of a secondary 
pair of ocellar bristles. These bristles are present in all of the 
Calliphorini, although usually they are much weaker and not 
well differentiated from the surrounding hairs. Coquillett's 
species, Calliphora lata, descril)ed from Japan, also appears to 
f)e a synonym of vomitoria. It might be considered a variety 
characterized chiefly by its more yellowish and somewhat shorter 
forceps of the male. 

A very curious situation exists in the genus Calliphora. Most 
of the specimens of C. vomitoria, erythrocephala and znridcscens 
in collections are females, while those of coloradensis are males. 
The species are very closely related, seimrated on what appeared 
to be slight and probably variable, or secondary sexual char- 
acters. It was thought that both viridcsccns and coloradensis 
would prove to be synonyms of erythrocephala. A character 
apparently insignificant in itself, however, was found for 
erythrocephala which appears constant for this si>ecies and on 
the basis of this character (the basicosta, which overlaps the 
extreme base of the costal vein, is yellow and the alar epaulet, 
immediately basad of the basicosta, is more or less yellow; in 
all other species black) the specimens of erythrocephala were 
segregated, leaving the characters of the two other species 
showing to much better advantage as constant specific struc- 



lures. Certain individuals, both sexes, of Calliphora vomitoria 
have pure black beards; hence it is necessary to rely on the 
number of intra alar bristles to separate them from viridcscens, 
as well as the forceps of the males which offer the best diag- 
nostic characters. These black bearded specimens occur in 
various parts of the country, and in order to emphasize that 
such forms occur and are liable to be confused with viridcscens, 
as they have been in the past, a varietal name, nigribarba, is 
proposed for them. C. morticia, a new species herein described 
from Alaska, may be confused with nigribarba but the para- 
facials of nigribarba are three times the narrowest widtli of 
the front in the male; the subquadrate bucca of this form is 
noticeably longer than broad in morticia and the male forceps 
further distinguish them. 

Certain biological features have recently been noted in the 
Callipliurini. J^arker in Psyche, p. 12^, PJ22, ix)ints out the 
ix)ssil)ility of pedogenesis in C. cryihroccphala. C. latijrons 
ap])ears to be larviparous, likewise Stcringomyia aldrichia, 
Peniales of both species, in the collection, have early stage 
maggots protruding from their ovipositors. 

'I'hc number of bristles in what has here been termed the 
sublateral row (11. VI) appear very constant in the genera 
Cynomyia, Sicnngomyw and Calliphora, numbering one, two 
and three, respectixely, and are used as the main means of 
classifying them. Idle only exception to this character among 
these genera so far noted occurs in the single male specimen we 
possess of Stcringomyia alaskcnsis, A very much reduced pair 
of anterior sublaterals (normally al)sent in this genus) is pres- 
ent on this s|)ecimen. Additional material may prove this pair 
normally absent for this species. These bristles in Onesia, 
however, differ in number, according to species, ranging from 
one to three. 1'hey also show some variability within the 
species. Oncsia ap])ears the most plastic of the Calliphorini, 
showing variations in other res])ects. Even the male geritalia 
are much more varied among the species than in the other 
genera. In our recently imi)orted O. agilLs Mg. and aculcata 



Pan. there are three sublaterals. These two species are well 
characterized by their elongated front, black head and rather 
small antennae. The bristling of the fore tibia also shows good 
generic diagnostic characters for the first three genera, but in 
Onesia they vary from one to two, usually one. 

The characters used to separate the Phorminae from the 
Calliphorinae are rather difficult of discernment but are appar- 
ently the most reliable. The one “stem vein ciliated” ^ is found 
on the upper side of the wing ; while the subcosta sclerite with 
small black bristles ^ is on the lower side. So one or the 
other character may be seen regardless of the position of 
the wing. 

The post alar declivity is pilose in all the Calliphoridae except 
in our one or more American species of ProtocalUphora, The 
European species of this genus, coerula and asurea, besides 
having the post alar declivity sparsely pilose, have fairly long 
sparse black pile on the anterior end of the membrane between 
the squama and thorax. This pile is absent in our American 
species. Considering these two differences it appears certain 
that we do not have either of the European species.

Acrophaga Braucr & Bergenstamm, Zweifl. Kais. Mus., v, 1891, 
367 {Steringomyia and Acrophaga). (Genotype alpina Zett. 

The male of the Steringomyia genotype, stylifera Pok., has . 
an elongate, nude projection on the abdominal venter imme- 
diately cephalad of the cleft segment. This single, secondary 
sexual character does not justify the retention of a genus for 
this species alone, therefore, acting on Aldrich’s advice, the 
closely allied group Acrophaga is included in it.

The sjiecimen described below was compared with a European 
specimen of alpina and considered conspecific by the writer. 

Male, — Differs from S. aldrichia as follows: Front at nar- 
rowest width broader than para facial; lower two-thirds of para- 
facials bright orange, facial plate dull orange ; silvery pruinositv 
of head much more pronounced; arista plumose only one-half 
its length; face noticeably more projecting; no bristle beyond 
middle on inner surface of middle tibia (very prominent in 
aldrichia). Second segment of hypopygium much longer than 
broad (globose in aldrichia) ; inner forceps much longer than 
outer (vice versa in aldrichia) pointed; outer ones curved 
apically, pointed, provided with short stiff hairs. Squamae 
whitish. Length 10 mm. 

One male, Tennessee Pass, Colorado, 10,240 feet altitude.

Steringomyia aldrichia, new species. 

Male . — Head subtriangular, slightly higher than broad ; front 
at narrowest width narrower than parafacial ; head black, para- 
frontals and upper half of parafacials black with silvery pruin- 
osity; basal half of third antennal joint reddish; rest of an- 
tennae black; arista longer than antenna, plumose more than 
two-thirds its length ; bucca black with rather stiff black hairs. 
Mesonotum bluish black marked with dull pruinose stripes. 
Abdomen steel blue, with silvery pruinosity; long bristles on 
latero-posterior margins of ail segments and long bristles ex- 
tending across posterior margins of second and third segments ; 
disc of fourth tergite with scattered long bristles and scattered 
short stiff hairs. Squamae darkened ; wings slightly infuscated. 
Inner forceps shorter than outer; outer ones thin, blade-like, 
pointed, provided with dense short stiff hairs on inner margin 
and shorter and sparser ones on outer margin; hypopygium 

Female . — Front a little longer than broad ; a secondary pair 
of weak ocellars directly behind hind ocelli. Three pairs well 
developed marginal scutellars, one pair discal scutellars; abdo- 
men less hairy than in male. Length 7-10 mm. 

Six males and two females, Tennessee Pass, Colorado, 10,240 
feet altitude, J. M. Aldrich, collector ; one male, Seward, Alaska, 
July 24, 1921, J. M. Aldrich; one male, London Hill Mine, 
Bear Lake, 7,000 feet altitude, British Columbia, R. P. Currie, 

Type. — Male, allotype, female, U. S. N. M., Cat. No. 26163. 

The two last specimens mentioned show some slight variation 
but it is thought not to be sufficient for specific diagnosis. 

One female shows an early stage larva protruding from the 
ovipositor ; hence it is assumed the species is viviparous. 

Steringomyia alaskensis, new species. 

Male . — Differs from S. aldrichia as follows: Parafrontals 
touching just below ocellar triangle; head bristles smaller and 
jveaker ; arista somewhat shorter, aristal rays noticeably longer ; 

INSECUTOR INSCm^ menstruus 


abdominal bristles weaker and fewer ; inner forceps very broad 
basally, gradually tapering to points, flattened on posterior 
aspect, as long as outer, densely clothed with very short stiflf 
hairs; outer forceps blade-like, pointed, densely clothed with 
short stiff hairs. 

Female , — One specimen from Alaska which may prove con- 
specific with alaskensis differs from aldrichia by its broader 
(quadrate) front, weaker head bristles; lowermost fronto- 
orbital on level with sixth frontal bristle; weaker abdominal 
bristles with which longer hairs are intermixed. Length 7.5 mm. 

One male, Seward, Alaska, July 26, 1921, J. M. Aldrich, 
collector; one female, Saldovia, Alaska, July 2, 1899, T. Kin- 
caid, collector (Harriman Exi>edition). The male shows two 
very weak anterior sublateral bristles, the absence of which is 
considered one of the chief generic characters for Stcringomyia; 
although the female tentatively placed with the male has them

tend to enclose inner ; outer ones obtusely pointed ; hypopygium 
globose. Wings slightly infuscated basally ; squamae white with 
pale cilia on outside hinge of upper and lower squamae and 
black hairs on disc of lower squama. 

Female , — Frontal vitta over twice as long as broad; lower- 
most fronto-orbital bristle on level with seventh frontal. 
Mesonotum with more pruinosity than in male; abdomen dis- 
tinctly greenish.

be merely a hairy form of mortuorum (Aldrich).

Type, Musca crythroccphala Meigen, by original designation (as 
vomiiorui Linne) 

In s]>ite of the abundance of individuals and fewness of 
species belonging to Calliphora (sensu stricto) well known as 
blue-bottle or blow-flies, they have proved one of the worst 
groups for the systeniatist and many misidentifications are 
extant. Some of the main characters used are unreliable, while 
others, which were believed variable, prove to be more stable 
than supposed. It is hoped that the characters here used, both 
genetalic and external, will clear up some of the mooted points. 

Calliphora vomitoria Linne, J^auna Suec., 2nd ed., no. 1830, 

p. 452 {Musca). 

North American synonyms : Calliphora fulznbaris Desv. ; C. mgri- 
hue CO Hough, a nomen nudem (from the name it appears that 
the specimen, or specimens, were the black bearded form of 
vomitoria); C. ruhrifrons Townsend; C. iraxuana Townsend, a 
varietal form. 



C. vomitoria is the most robust of the CaJliphora. Its general 
color is also darker while the amount of silvery pruinosity on 
the abdomen is very slight. It has been chiefly characterized 
by the red beard but the writer has seen black bearded forms 
from widely scattered parts of North America. The species is 
apparently holarctic in distribution. 

C. vomitoria nigribarba, new variety. 

Differs from vomitoria only by having the beard black instead 
of red. This form is usually associated with C. viridcsccns in 
collections. There are at hand specimens from Narrows, Mt. 
Desert, Maine ; South West Harbor, Maine ; Whiteface Moun- 
tains and Mount Marcy, Adirondacks, New York ; Kulak Bay, 
Alaska; Moores Lake, Idaho; Fallen Leaf, California. 

C. vomitoria irazuana Townsend, Muscoid Flies, 1908, 118. 

This form described as a distinct species is a dark bearded 
form of vomitoria which has the wing bases unusually darkened. 
(Aldrich synonymy, on basis of male genitalia.) 

Calliphora elongata Hough (Snn.). 

Cynomyia elongata Hough, Ent. News, ix, 106 . 

Cyrunnyiopsis elongata Townsend. 

This species apparently is a rare one and as far as known 
has been collected but twice since the original series were de- 
scribed in 1899. Dr. J. M. Aldrich took several specimens, 
males and females, in South Dakota, and Dr. W. M. Wheeler 
captured specimens in Wyoming. The National Collection has 
a cotype male and female, taken in copula ; a cotype male and 
female are in the Hough Collection at the Field Museum, Chi- 
cago; while Aldrich has seen in the Kansas collection four 
males from Creede, Colorado, in poor condition but with 
forceps spread. 

Calliphora morticia, new species. 

Differs chiefly from inridescens in having the head as high 
as broad (broader than high in viridcsccns ) ; head except eyes 
entirely black, parafrontals and parafacials provided with sil- 



very pruinosity (two females probably teneral have a reddish 
spot above antennae and the face partly reddish). The forceps 
of the male differ from those of znridescens in being more elon- 
gate and gradually coming to rather a blunt point and instead 
of having long sparse hairs are provided with dense short stiff 
hairs below and still shorter hairs above. The apex of the 
forceps of viridescens takes a sudden curve and becomes sharply 
pointed. The species is somewhat smaller and more slender 
than the average viridescens and the mesonotum is less pruinose.

U. S. N. M. Type. Cat. No. 20102. 

Calliphora viridescens Robineau-Desvoidy, Myiodaires, 437, 

This species appears to be the least common of the Calliphora 
species. Only five authentic males have been seen by the writer, 
ir^pecimens at hand are from Melrose Highlands, Massachu- 
setts; Ithaca, New York; Plummer’s Island, Maryland; Colum- 
bus, Ohio; St. Louis, Missouri; Georgia; Lowe’s Inlet, British 
Columbia ; Lafayette, Indiana ; Moscow, Idaho ; Stratford, 
Washington; Harvey’s Ranch, New Mexico. 10,000 feet. 

Aldrich has ascertained through Villeneuve that the so-called 
synonym violacca Meigen of this species is in reality Phormia 
regina. Dr. Villeneuve examined one of our North American 
spread males and reports the species distinct from any at 
present known in Europe. 

Calliphora latifrons Hough, Zool. Bull., ii, 286, Washington, 
Idaho, California, Mexico. 

Townsend makes this species type of BucalUphora, basing it 
on insufficient characters, hence genus not accepted (Aldrich 
and Shannon). 

A common species found in the west in British Columbia 
and southward into Mexico. 



Calliphora eiythrocephala Meigeo, Syst. Beschr., v, 62 
(Musca), Europe. 

The distinct yellow to orange color of the basicosta in this 
species in contrast to the black basicosta in the others serves 
for immediate identification of this species. 

Distribution : Reported from all parts of the United States. 

Calliphora ccdoradensis Hough, Zool. Bull., ii, 286, Colorado. 

Walton, Proc. U. S. Nat. Mus., xlviii, 176, says is common in 
prairie-dog town, flying into burrows. One female in collec- 
tion shows early stage larva protruding from ovipositor. 

Distribution; Western United States. Apparently coexten- 
sive with C. latifrons.

I have recently become convinced that we have here to do 
with a single species of wide distribution — Brazil to the southern 
United States and probably the Antilles. Formerly it seemed 
necessary to apply different names to the forms of separate 
localities, and the apparent intervention of a species in Mexico 
having the same genitalia but different larvae {mutator D. & K.) 
lent weight to this view. The previous discussion clears up that 
matter and paves the way for a broader distribution. As the 
males and larvae are alike throughout, or at least as far as 
known, I think this may be accepted. Theobald and the earlier 
authors confused this species with atratus Theob., a species 
confined to the Antilles and having very different males and 
larvae, although similar coloration, I am not yet certain of the 
synonymy of pose D. & K. It is true that 1 identified males 
from Louisiana as that species (Dyar, 19^;^), but a long series 
from Mr. Bradley shows the gold of the mesonotum gradually 
fading out. I await Texas material l>efore deciding positively 
as to pose. 

In several keys and descriptions I have given the spine of the 
mesosomal plate of the male hypopygium as being subapical. 
The appearance changes with the position of the mount; but 
leprincei should l>e described as medial on the stem. Only in 
mutator (alfaroi) is the spine really subapical. 

Culex (Melanoconion) panocossa, new species. 

The Panama representative of Culex {Melanoconion) 
aikenii Aiken (= Gonphodeomyia inornata Theob. = Culex 
ocossa D. & K.) of British Guiana and Surinam; but the dif- 



ferences appear to be specific rather than racial. In the male 
hypopygium the side-piece at tip has on the outside a dense tuft 
of curved hairs ; subapical seta on the inner side is a true seta, 
stout, but not flattened; the stem of the outer division of the 
lobe, and that of the inner division also, are much longer, the 
latter being distinctly longer than its appendages, whereas in 
aikenii the reverse is the case. 

Nineteen specimens of both sexes, Bas Obispo, Canal Zone, 
Panama, bred from larvae among the roots of Pistia, Feb- 
ruary, 1923 (J. B. Shropshire). 


{Dipt era, Culicndae) 


Dr, C. Bonne and the writer endeavored to fix the identity 
of the five species of Culcx described by von Humboldt in 1820. 
I'hc descriptions occur in the work by Humboldt and Bonpland ; 
but it is stated that Humboldt himself made the descriptions 
from specimens in the field, which he apparently did not take 
the trouble to bring home. Mosquitoes were captured in large 
numbers, he tells us, and it would api)ear that these were spread 
before him, and the conspicuous and brilliant ones selected for 
description, and then the mass discarded. The descriptions 
were evidently made with the naked eye or a very weak lens, 
from the material lying on a cloth or paper without lifting the 
wings, so that abdominal s]:)ots could not 1^ distinguished from 
bands. Dr. Bonne objected to some of my suggestions on the 
ground that the species described are rare ones, whereas he 
supix)sed that von Huml^oldt would describe the common ones 
only. My opinion is different, namely, that a great number of 
specimens were taken in a rich and abundant locality and 
season, from which the conspicuous ones were selected. In 
such a fortunate catch, doubtless the whole fauna was repre- 
sented, so that the (juestion of rarity need not trouble us. With 



these considerations in mind, I make the following identifica- 
tions : 

Cuiex cyanopennis von Humboldt is Psorophora tibialis R.-D. 

Culex lineatus von Humboldt is Psorophora saeva D* & K. 

Cuiex ferox von Humboldt (1820) is Psorophora posticatus 
Wied. (1821). 

Cuiex chloropterus von Humboldt is Sabethoides nitidus 

Cuiex maculatus von Humboldt (1820) is homonymous with 
C. maculatus Meigen (1804). The description cannot apply 
to any mosquito, and in any case the name falls as a

Sabethes kappleri, new species. 

Female: Proboscis rather short, swollen at tip, dark blue. 
Palpi about one-fourth of the proboscis, blue-black. Clypeus 
rounded, dark, white pruinose. Occiput clothed with iridescent 
greenish blue flat scales. 

Prothoracic lobes collar like, iridescent blue. Mesonotum 
covered with elliptical, flat, greenish blue iridescent scales. Scu- 
tellum with similar coloration. Postnotum with four setae on 
posterior part and some greenish scales. Coxae and pletirae 
with patches of silvery scales. 

Abdomen compressed, truncate at tip, dark dorsally, white 
beneath, the colors separated in a straight line. 

Wings narrow, smoky; petiole of second marginal cell less 
than half as long as its cell, that of second posterior cell longer 
than half its cell. Basal cross vein about its own length from 
anterior cross vein. Scales of veins elliptical, some of them 
truncate. Halteres blackish.

tibiae blue with outstanding blue scales on distal half, forming 
a small paddle, first two tarsi blue, last three tarsi white, with a 
dark shade on one side. 

Mid legs : Distal half of tibiae, all of first and second tarsal 
joints with large outstanding scales forming a blue and white 
I)addle ; scales on tibia and first tarsal blue, second, third and 
basal half of fourth tarsal snowy white, apical half of fourth 
and whole of fifth tarsal blue. 

Hind legs: Femora blue, lighter beneath and white beneath 
on basal fourth, tibiae and tarsal joints blue but the two last 
joints white beneath. 

Claw formula 0.0~0.0~0.0. 

Length: Body about 6 mm.; wing 5 mm. 

Differs from goeldii H., D. & K. and schausi D. & K. by the 
absence of paddles on the hind legs and also by the absence of 
white above the paddles on the mid legs. Differs from tarsopus 
D. & K. by the absence of white above the paddles of the mid 
legs and the extension of the white on the front legs. 

Only one specimen was captured, in the woods attacking in 
daytime; February, li)23, Moengo, Surinam. Already when 
flying it was easily recognized as different from bipartipc^ 
D. & K., the common Sabvthes with white on the mid legs at 
Moengo. Unfortunately I did not have anything to catch it 
with, so I had to crush it and damage it considerably. It will 
be deposited in the Museum of the Institute for Tropical 
Hygiene, Amsterdam, Holland.

(Diptera, Culicidae) 

By C. bonne 

Howard, Dyar and Knab report considerable variation in 
the extension of the black spots on the costa of the wing. I can 



confirm this from material collected in Surinam, which also 
shows variation in the extension of the white on the hind legs. 
Howard, Dyar and Knab describe this species with the white 
on the hind legs on the apical half of the second joint, all of 
the third and fourth joints and the apical half of the fifth 
joint. Panama specimens show the white accordingly. In 
Surinam the white is usually more extensive and present on the 
apical four-fifths of the second joint ; the other joints show no 
differences. Specimens with only the apical half of the second 
joint of the hind legs white are occasionally seen also, but much 
rarer, and much rarer still are intermediate forms with the 
white on the distal two-thirds. 

There seem to be certain differences in life habits between 
tarsimaculata from different places and it may be worth while 
to pay attention to the small differences in coloration. In the 
Canal Zone tarsimaculata and albimanus are caught in houses 
in large numbers. At Moengo in the interior of Surinam 
tarsimaculata is practically never caught in houses although it 
breeds extensively at Moengo ; argyritarsis has taken its place. 
Tarsimaculata can be found always in cowsheds, however, 
where argyritarsis is not so common.

Goeldia trichopus Dyar, 

Male. Palpi two-thirds as long as proboscis. 

Hypopygium. Side piece long and slender, about four times 
as long as wide, conically tapered toward tip; basal lobe large, 
conically pointed, densely covered with long hairs; a group of 
closely placed long stiff hairs on each side piece near its base 
and all over the side piece very long coarse hairs. Clasper 
moderate, very slender, the base inflated, with terminal ap- 



pendage. Tenth sternites prominent, with thickened inner 
margin and a few strong curved teeth on tip. Lobes of ninth 
tergite capitate with six long, coarse, terminal spine-like bristles. 

One male was captured in a house in Surinam. 

Croeldia longipes Fabricius. 

Larva. Head rounded, quadrate, longer than wide; mouth- 
parts not visible from above, though strongly developed and 
heavily armed. Antennae slender with a single hair at outer 
third. Head hairs single. Mental plate broadly triangular, 
more or less divided into three plates, middle plate bearing a 
stout central spine with two minute spines on each side ; lateral 
plates each with nine teeth, the third and fourth being most 
prominent. Air tube moderate, flared at base, spicular pilose; 
a row of densely placed tufts of three or four long very fine 
hairs along ventral line, running from base to tip, in all about 
thirty-two tufts. Lateral comb of eighth segment of many 
sharply pointed spines in a patch. Anal segment about as long 
as wide with a dorsal plate; dorsal tuft consisting of a group 
of five and a group of ten long hairs on each side ; lateral hair 
single, long, arising from angle to plate; subventral tufts mul- 
tiple, long. Anal gills long, at least five times as long as anal 
segment, tracheae stout. 

Dyar recently (Ins, Ins. Mens., vi, Si) made culicivora Dyar 
and Knal) a synonym of longipes. The larva of culicivora has 
only four spines on the eighth segment; longipes has a patch 
with a large number a spines in three rows. We found the 
larvae several times in Surinam in the jelly-like mass between 
the Jeaf -stalks of Hcliconia and Ravenala, feeding on Wyeomyia 
(Cleobonnea) occulta B.-W, & B.

In a recent article by Mr. A. N. Caudell (1922, Ins. Ins. 
Mens., X, 112), Danby and Green are given credit of author- 
ship of certain names, viz. : 



Pleroma apposita, Xylomiges Candida, X, cognata, X. pul- 
chclla, and ''Taeniocampa^* ferrigera; because of the publication 
of figures in the Bull. N. H. Soc. B. C., 17-18, pi. I, dated 1893. 
Dr. Smith’s descriptions were published in 1894 (Trans. Am. 
Ent. Soc., XXI, 78 et seq.), except F. apposita which was 
described and figured by Smith in 1892 (Ent. News, III, 262, 
pi. X). 

From the dates printed on the publications, Danby and 
Green’s paper would appear to have had a year’s priority. 

Mr. E. H. Blackmore furnishes the following data. 
(1) Proof copy of Danby and Green’s paper, dated Jan. 15, 
1894, in Mr. Danby’s handwriting. (2) No trace of minutes 
of the B. C. Ent. Soc. exist earlier than 1902. (3) ‘T have 

tried the Gov’t Printing Office but none of their earlier records 
are existent.” (4) Mr. Green is alive but knows nothing of 
the publication of this paper. 

Librarians at the following libraries were consulted: Nat.

Ont. ; Ont. Agr. Col. ; Can. D. A. ; Cong. ; John Crerar ; Phila. 
Ac. N. S. ; Mus. Comp. Zool. ; Bost. Soc. N H. ; Brit. Mus. 

The earliest date received for the 1893 Bull. N. H. Soc. B. C. 
is March 20, 1896 (British Museum). 

The earliest date received for the Trans. Am. Ent. Soc., 
XXI, 78, is April 14, 1894 (Cornell University) . 

Capt. N. D. Riley (British Museum) furnishes the follow- 
ing data. 

”Our copy of Trans. Am. Ent. Soc., XXI, PP. 39, 88 was 
received here 2/5/94. That of Bull. N. H. Soc. Br. Col. on 
26/3/96. This later paper is, I see, referred to in the Zool. 
Record for 1895, and, most unaccountably, one of the papers 
(Newcombe’s Mollusca) got into the record for 1893 yet in- 
cludes reference to a paper published in the Trans. Ottawa Field 
Club, in Dec. 1893. I think there can be no doubt however 
that it was not published in 1893; in fact I should have no 
hesitation in giving the Am. Ent. Soc. paper priority.” 

Unless further data regarding an earlier receipt of the Bull. 



Nat. Hist. Soc. B. C. be received, Smith’s name should be 
retained as author for the species in question.

The following undescribed species of Prinota van der Wulp 
was included in some extensive collections of crane-flies 
belonging to the Paris Museum and sent to me for determi- 
nation through the kind interest of Mons. Eugene Seguy. 
The unique type is in the collection of the Paris Museum. 

Prionota s6guyi, new species. 

General coloration obscure orange, the praescutum with 
three slightly darker stripes; wings pale brown, the coastal 
region darker ; cell short-petiolate ; basal abdominal tergites 
not conspicuously brightened. 

Female , — Length about 27 mm.; wing, 20-21 mm. 

Head black, the genae light gray pruinose. Antennae black, 
the bases of flagellar segments 1 to 4 indistinctly ferruginous. 

Mesonotum obscure orange, the praescutum with three 
darker, rust-brown stripes, the broad median stripe entire 
(narrowly divided by a pale vitta in P. nigriceps Wulp). 
Wings weakly tinged with brown, the costal region with dark 
brown, this darkened area including cells C. Sc, rst R^, 2nd Ry 
and stigma still darker brown; wing-root pale brownish 
yellow ; a brown wash in cell My and another along vein 2nd A, 
Venation: Cell My with a petiole that is approximately equal 
to m; ntrcu distinct. 

Abdominal tergites dark brown, very inconspicuously varie- 
gated with ferruginous, the basal segments not conspicuously 
brighter than the terminal segments; basal stemite? fer- 
ruginous, margined caudally and laterally with dark brown; 
terminal stemites uniformly dark. 



Habitat. — Java. 

Holotype, Soekaboemi, 1919 (E. S4guy). 

This interesting crane-fly is named in honor of Mons. 
Eugene Seguy. 

The genus Prionota was erected by van der Wulp (1885) 
for the supposedly undescribed species, P. nigriceps (Java). 
As has recently been pointed out by Edwards, this species is 
doubtfully distinct from the Ctenopkora xanthomelaem 
Walker (1848). In 1912 Enderlein described a distinct species 
from Sumatra under the name Prionocera flaviceps. In 1921 
Enderlein erected the genus Plocimas for a new species from 
southeastern China, described as P. magnificus. To this genus 
I would refer the Pselliophora serraticornis Brunetti (1911), 
and P. ? clongata Edwards (1913), both from Ceylon. Mr. 
Edwards {in litt.) informs me that the two species are synon- 
ymous. We thus have two closely allied genera. Prionota with 
a single serration on the lower side of each flagellar s^^ent, 
Plocimas with two such serrations, one being basal, the other 
apical. The synonymy of the two genera may be outlined as 
follows : 

Prionota van der Wulp; Notes Leyden Museum, 7: 1-2; 

P. nigriceps van der Wulp; 1, c., 7: 2-3; 1885. (Doubtfully dis- 
tinct from the next).

Bv W. H. W. KOMP 

During the year 1922, in the course of malaria research 
studies which were carried on under the direction of Special 
Expert M. A. Barber, U. S. Public Health Service, several 
pools on the outskirts of the town of Brewton, Alabama, were 
kept under constant observation. One pool was an old rail- 
load borrow-pit, another a large pool in an open pasture, and 
another a low, water-logged area between two cultivated fields. 
Third-stage larvae of Culcx floridaniis D. & K. were found 
in a small grassy pool separated from the main body of water 
in the railroad borrow-pit July 21. Several of the larvae 
transformed in the laboratory, and a male emerged a few days 
later. Collections made August 3 in the water-logged area 
showed full-grown larvae of C. floridamts, and a day later 
several pupae were collected. Follovsing thi‘^, a prolonged dry 
spell ensued, broken by thunder-showers of short duration 
<")n Octol)er 2 a heavy rain fell, and seven days later the large 
|)Ool in the pasture was examined. This pool bad been dry 
for thirty-one days previous, the dried mud in the ]x>ttoni 
being cracked and fissured to a depth of an inch or more. 
Several dozen pii})ae of Culcx floridamts were collected at this 
time, associated wdth small Anot^heles crucians larvae, and 
pupae of Psorophora discolor. A second search of the pool 
October 10 showed several more pttpae, and a single dead 
larva of C. floridanus, ])robably killed by an application of 
Paris green made to destroy Anopheles larvae. The railroad 
borrow-pit was examined October 11, after its numerous 
depressions had been filled with rain, after a protracted dry 
spell. Large numbers of Culcx ftoridauus larvae were found 
in these grassy ix)ols, and, indeed, after the rains of October 
2, 7 and 8 and thereafter, the larvae were common in almost 
every pool and ditch that was examined. The last collections 
in the neighborhood were made November b, and large num-

bers of this species were noted in the grassy bottom of anti- 
malaria drainage ditches dug earlier in the season. A close 
watch was kept for eggs, but no egg-masses were found any- 
where. The females were not observed to bite at any time. 

These observations may be summarized as follows: Culex 
floridanus larvae were first found July 21, in a grassy, semi- 
permanent pool, later in permanent water with aquatic vege- 
tation, and again in a pool with muddy bottom and almost 
no vegetation, which had been dry for thirty-cwie days previous 
to the rainfall which then filled it. After the heavy fall 
rains the larvae were common in ditches and pools filled with 
rainwater. The three pools mentioned above had been under 
constant observation from January, 1922. Large numbers of 
larvae were observed as late as November (>. The egg-laying 
habits were not observed, but seem to be f)eculiar, as the sea- 
sonal history points to an overwintering egg, with possibly 
but a single brood, as in several species of Aedes. 

The larvae of Culex floridanus are unique in possessing 
accessory tracheal gills borne as appendages on the head. So 
far as is known, this is the first recorded occurrence of such 
structures in a Culicid. They are adaptations permitting the 
larva to remain at the bottom of the pools which it inhabits. 
The mouth-brushes are very well developed, and are kept in 
constant motion, thus causing a current of water to flow over 
the gills, which are full of minute tracheae. The gills are 
paired appendages, the larger and more noticea)>le ones arising 
from the membrane at the base of the antennae, the others 
from the intersegmental membrane near the insertion of the 
maxilla and the mandible. This latter pair is attached in such 
a manner that they move with the maxillae and mandibles 
when the larva is feeding. This movement also aids in aera- 
tion. The large gills are stalked, ovoid in shape, with a large 
trachea passing up the stalk, dividing into many anastomosing 
branches in the body of the gill. The smaller gills are com- 
posed of two parts, a large club-shaped portion and a smaller 
portion branching dichotomously. The relative size, shape 
and position of these structures may be easily discerned by 

INSECUTOR insciti^ menstsuus 


reference to the accompanying drawing (PI. IX). In fresh 
specimens it is possible to trace the tracheae frmn the gills 
down through the head, into the neck, and thence to widen- 
ings of the main tracheae, which form air-sacs in the thorax. 

Since this structure has been observed, similar but not nearly 
so well developed tracheae have been observed in another 
species of Culex found in the same locality. In Culex erroHcus 
D. & K. the membrane at the base of the antennae is provided 
with a plexus of small tracheae, and a similar plexus is found 
in the membrane laterad of the insertion of the mandible and 
maxilla. The mouth-brushes of this species are well-devel- 
oped, also, but it has not the habit, so marked in Culex 
fioridanus, of lying on its back on the bottom, or hooking itself 
up by the strong terminal hooks of its air-tube, and feeding 
by causing a current of water to flow toward its mouth by 
the action of its large mouth-brushes. The larvae of Culex 
fioridanus are very characteristic in appearance and actions 
as the accessory gills are prominent, and the breathing-tube 
with its long hair-tufts is held well forward over the dorsum 
of the abdomen, like a terrier’s tail. When disturbed, the 
larva goes to the bottom, moving the posterior end of the body 
in short, quivering je'ks, very much like the larva of Psoro- 
phora discolor Coq. in similar circumstances.

The genitalia of the male are identical with those of the 
holotype of L. barnesi and both sexes can be easily matched 
with topotypical material from Arizona. 

The Barnes Collection contains one female labeled “Oak 
Creek Cany., Col.,” and another females “Miles City, Mont.,” 
from the Jacob Doll Collection, which were omitted from the 
revision of the genus (see bibliography) as questionable. 
These localities, in view of the Michigan specimens, are prob- 
ably correct. 


(Dipt era, Syrphidae) 


During the determination of some Diptera in the Canadian 
National Collection, I discovered a species of Scricomyia 
which I thought must be undescribed, but further study 
revealed the fact that it is the female of 5*. bifasciata Willislon. 
The only guide to the identity of the species wUs found in the 
face, other characters differing rather markedly. A second 
specimen which belongs in the same category was found in 
the United States National Museum during a visit last winter, 
and is imdoubtedly the male of S. sexfasciata Walk, notwith- 
standing the remarkably different aspect of the insect. I give 
a full description of the undescribed sexes of these two species 
owing to the dimorphism.

thinly yellowish pollinose, leaving a geminate median stripe 
more shining in certain lights. Pile on pollinose portion and 
narrow upper margin of pleura, yellowish, elsewhere black, 
not long. Scutellum concolorous with thorax, wholly black 

Femora black, their apices narrowly reddish ; tibiae reddish, 
their middle half or more brownish, diffuse; tarsi blackish, 
the first joint reddish, the second brownish. Hind trochanters 
without spur. 

Wings yellowish anteriorly, the color fading to almost 
hyaline or cinereous posteriorly. Third longitudinal vein dis- 
tinctly curved upward beyond the middle of the first posterior 
cell, as in the female. Squamae and halteres yellow, the for- 
mer with yellow fringe. 

Abdomen opaque black, the first segment, lateial margins 
and apices of the segments increasingly more widely so, shin- 
ing deep black. Yellow fascia on second segment slightly 
oblique, their postero-lateral corner rounded, their hind mar- 
gins practically straight, inner ends slightly narrowed, sharply 



rounded in front, their outer ends occupying nearly one-third 
the length of the segment as it is rather suddenly triangularly 
produced forward, rather narrowly interrupted. The bands 
on the third and fourth segments are similar in shape but 
only slightly widened laterally, nearer the front margin and 
very narrowly interrupted. Fourth segment half shining. 
Pile black, except a few hairs laterally on apical segment and 
most of the ventral hairs. 

The specimen from which this description is drawn is from 
Franconia, New Hampshire (Mrs. Slosson). There is another 
specimen in the Museum of Comparative Zoology at Cam- 
bridge. Tlie female has the first abdominal band extremely 
broad, the two following broad, widest medianly. The pile 
of the pleura, front half of dorsum and whole margin of 
posterior half, and basal two abdominal segments whitish or 
pale yellow. The legs are darker, the wings almost hyaline. 

Sericomyia bifasciata Williston. 

Face produced conically downward, with a median black 
stripe, scutellum black; abdomen with three transverse nar- 
rowly interrupted reddish bands. 

Female . — Length 11 mm. Face honey yellow, thinly cov- 
ered with pale yellowish pollen; a median stripe, narrow oral 
margin and cheeks, shining black ; in profile almost perpendicu- 
lar, the tubercle rather long and conspicuous; produced so 
that about two-thirds of the face is below the eyes. Sides 
of face, extending above to the base of the antennae, pale yel- 
lowish pilose. Front shining black, the sides below', connected 
w'ith a narrow band on the lower third, thickly pale yellow 
pollinose; pile black, not long nor abundant. Occiput with 
yellowish pollen, which becomes grey above, and yellow pile. 
Antennae piceous, the third joint more reddish below. Arista 
black, or brown, the black hairs forming the loose plume about 
one-fourth as long as the arista. 

Thorax shining black, the dorsum with a bluish reflection in 
some lights; humeri and a less dense band between, greyish 
white pollinose. Pile brassy yellow, longer on the sides and 



pleuta. Scutellum concolorous with the dorsum of the thorax, 
with similar pile. 

Femora black, the apices reddish, more broadly so above. 
Tibiae reddish, on the outer side with obscure median spot 
of blackish or brown. Tarsi reddish, the last three joints 
brown or black. 

Wings cinereous hyaline, yellowish before the fourth longi- 
tudinal vein to about the middle, where there is a slightly 
darker area extending almost to the anal vein along the veins 
at the apex of the second basal cell. The cinereous color is 
a little condensed apically in the marginal and submarginal 

Abdomen opaque black; first and fifth segments wholly, 
sides of all the segments and the rather broad hind margins 
of the second, third and fourth, shining black, but because 
of the bright pile appearing more or less brassy on the terminal 
segments. All the bands transverse, placed a little before the 
middle of the segment, their outer ends broadest, so that the 
black before and behind is about equal; the front margin 
transverse, the hind slightly oblique : inner ends sharply 
rounded, the outer truncate. The bands are all separated 
from each other medianly by the same interval; the first band 
reaches the lateral margin by a prolongation forward and 
extends to the base of the segment where there is a small 
reddish transverse spot; the bands on the third and fourth 
segments are narrowly separated from the lateral margin. 
Pile bright yellow, appressed; on the sides and terminal seg- 
ments longer, erect. Sternites blackish blue, the incisures 
narrowly reddish; the base of the second segment rather 
broadly diffusely reddish; membrane ftiscous, with a reddish 
spot opposite the incissures.

same data. 

The 5 is similar to lappona, of Europe, and is probably the 
one on which that species was recorded from Quebec by Van 



der Wulp. It differs from lappona by the conically produced 
face, black bases of the femora, smaller size, etc. Very similar 
to chaicopyga, but the face is longer, the femora more ex- 
tensively black, the abdominal bands wider laterally and nar- 
rower medianly and the venter has not distinct yellow seg- 
mental apices. From cynocephala Hine it is distinguished by 
the black facial stripe. It is readily distinguished from 
chrysotoxoides by the transverse bands and cannot be con- 
fused with any of the other described species.

{Lcpidoptera, Noctuidae) 


The larvae of Hyblaea piiera Cramer were found abundantly 
on a large tree in Kingston, Jamaica, which has been deter- 
mined as Catdpa longissima (Jacq.) Sims, by Mr. Paul C. 
Standley. Having only a few hours ashore from the boat,' 
what material could be found was hastily collected, and unfor- 
tunately, the specimens of larvae secured pupated before a de- 
scription could be made. The larvae are spun up in the leaves 
in tight cases, such as made by Pyralids, and their general pale 
color and weakly striped markings also resemble those of 
I^alids. The larvae of the species of Dichogam which I 
formerly found in Florida present a similar general appearance.

( Dipt era . Cu ficida4‘ ) 


The mosquitoes of Panama were first systematically inves- 
tigated by Mr. August Busck, who visited the Canal Zone and 
adjoining portions of Panama in 1907. Subsequently extensive 
collections were made by the late Allan H. Jennings. Mr. James 



Zetek and Major L- H. Dunn made still later collections, while 
in the last few years Mr. J. B. Shropshire has sent in extensive 
material secured in the now completely sanitated areas. Con- 
siderable changes in the mosquito fauna have been wrought by 
the construction of the canal, with the flooding of the Chagres 
valley, the destruction of the forest and the extensive sanitation. 
This latter has been undertaken as a permanent work, the 
swamps being filled, ponds eliminated and surface water carried 
in concrete drains. In many areas, therefore, no mosquitoes can 
now be found where formerly many species were recorded. 
Moreover, all the bamboo formerly growing along the Chagres 
River has been destroyed, not a clump remaining, and the mos- 
quitoes addicted to this plant, some fifteen species, have almost 
completely disappeared from the Zone, and must be sought in 
less disturbed regions. The present list is offered, based on 
species recorded up to the year 1922, as a basis for further 
work. New synonymy, here first recorded, is briefly explained.

Phomomyia chrysomus Dyar & Knab, Journ. N. Y. Ent. Soc., 
XV, 208, 1907. 

The type of Phoniomyia, as shown by Bonne-Wepster & 
Bonne (Ins. Ins. Mens., ix, 6, 1921) is longirostris from Brazil, 
restricted to a female t)rpe. This, according to Theobald’s 
original description and emendations, has the proboscis long, 
wing scales narrow, prothoracic lobes with metallic (coppery?) 
reflection; abdominal colors separated in a straight line; legs 
without white mentioned, but the legs of the type are now 
broken. The present species, chrysomus, differs only in having 
white on the mid tarsi. It may be the same as longiroHris from 
Brazil, but I have no specimens from outside of Panama. Cer- 
tainly the subgeneric characters seem to correspond, and I am 
therefore using Phoniomyia instead of Dendromyia of my 
former paper (Ins. Ins. Mens., vii, 124-126, 1919). In regard 
to the latter, Theobald says that the wing scales are “rather 
broad,’’ which would exclude it from present consideration.

cephala, the lobes are rubbed, but it agrees otherwise.

comb being really a patch of scales as described by Doctor

Omitting the names of those forms which are doubtfully the 
sexes of others, this list contains 128 species. Doctor and 
Mrs. Bonne give 136 species found by them in Surinam (Ins. 
Ins. Mens., xi, 123-127, 1923), and it thus seems probable 



that 130 species is about the number of mosquitoes that may 
be expected to occur in one tropical American region. In the 
case of Panama, it is possible that the list will be extended by 
further collecting, but I think not to any great extent. Super- 
fluous synonymy has been already pretty thoroughly eliminated. 
Mr. Busck published a list of Panama mosquitoes, including 
those taken by himself and otherwise recorded (Smith. Misc. 
Colls., Quart. Iss., lii, 49-77, 1908), in which he records 89 
species. Some of these were not taken by Mr. Busck himself, 
and others in the list have since been reduced to synonymy, 
so that the actual number of species collected by Mr. Busck at 
that time amounts to 76 species, from the records in the 
National Museum collection. This excellent start has been 
built upon for fifteen years, until the present record has been 


{Dipt era, Culicidae) 


A species of Culcx of the salinarius group occurs in the 
Federal District about Mexico City. The specimens have been 
received from time to time through Sr. A. L. Herrera, but 
always in such poor condition that it has seemed undesirable to 
attempt description. Recently, however, a long series has come 
from Sr. Regino Balanzario, a medical student, who desires a 
determination for use in his thesis. These specimens are in no 
better shape — ^they are completely denuded — but some males are 
included which are distinct on genitalic characters. The fol- 
lowing description is offered, based on the male genitalia: 

Culex federalis, new species. 

Lobe of side piece with three rods, a hooked filament, a leaf 
and a seta. Tenth sternites with the outer spines thick and 
tooth-like, the basal arm long and completely recurved. Mesa- 
some with two arms and denticles between, the tooth from the 
base wide and shortly projecting, indistinct, its origin not 



traceable ; outer arm tooth-like, strongly widening below apex, 
the widening forming a shoulder; lower arm tooth-like, mod- 
erate; denticles numerous, filling the space between the arms, 
somewhat curved, the upper ones next the outer arm small. 

Types, two males, mounted out of a series of 158 specimens 
of both sexes, Xochimilco, D. F., Mexico, presumably collected 
in the summer of (R. Balanzario, through A. L. Herrera). 


(Diptrra, Culicidctc) 


In this magazine (Ins. Ins. Mens., vi, !)2, 1918) I recognized 
a numl)er of subgenera of Culcx, of which reference is here 
had particularly to Micraedcs, Melanoconion and Isostomyia. 
The latter name 1 have shown (Ins. Ins. Mens., xi, 82, note, 
1923) is not properly applicable to a subgenus of Culex, but 
rather to a group of Goeldia. Further study and more extensive 
material has induced me to pro{X)se the following regrouping: 

Clasper simple, slender beyond the enlarged base. 

Lobes of sidc-piccc apart Melanoconion 

Lobes of side-piece united and reduced Micraedes 

Clasper simple, thick, narrowed on terminal third. 

Lobes of side-piece apart, but joined on a common stem to base, 


Lobes of side-piece united and reduced Tinolestcs 

Lobe a single long arm, followed by very large setae Eubonnea 

Clasper simple, bent near the middle at right angles or nearly so. Aedinus 
Cla.sper modified at tip. 

Tip obliquely elliptically excavate or branched Helcoporpa 

Tip swollen with snout-like termination Choeroporpa 

Tip swollen, subspherical Mochhstyrax 

Culex (Melanoconion) atratus Theobald. 

The type of the subgenus. The male hypopygium is shown 
on Plate XI, figure 10. 



Culex (Melanoconion) zeteci Oyar. 

The hypopgiutn is similar to that of atratus, the inner division 
of the lobe of side-piece is strongly developed (PI. XI, fig. 11). 

Culex (Melanoconion) dunni Dyar. 

In this form the transparent plate at base of side-piece is 
excavated and forms a blade-like arm (PI. XI, fig. 12). The 
ensiformis of Bonne- Wepster & Bonne is identical, as far as 
my limited material shows. 

Culex (Melanoconion) commevynensis Bonne-Wepster & 

The figure (PI. XI, fig. 16) is from a sketch kindly made 
for me by Dr. C. Bonne. The outer division of the lobe of 
side-piece is strongly developed and supplemented by a large 
flattened seta. 

Culex (Melanoconion) spissipes Theobald. 

This figure (PI. XI, fig. 17) also was made by Dr. Bonne. 
The palpi of the male exceed the proboscis as in all the species 
here referred to Melanoconion. 

Cul« (MicraSdes) bisulcatus Coquillett. 

The species is figured here for comparison (PI. X, fig. 6). 
The palpi of the male are only one-third as long as the proboscis. 

Culex (Gnophodeomyia) aikenii Aiken. 

In this peculiar form, the divisions of the lobe of the side- 
piece are united and partly separated from the lobe itself nearly 
to the base (PI. XI, fig. 13). The palpi of the male exceed the 

Culex (Gnophodeomyia) panocossa Dyar. 

Perhaps a geographical race of the preceding. The differ- 
ences in the structures, while considerable, are relative only 
(PI. XI, fig. 14). 

Culex (Tinolestes) latisquama Coquillett. 

This also is redrawn for comparison (PI. X, fig. 6). The 
'palpi of the male are only half as long as the proboscis. 



Cuiex (Eubotmea) tapena Dyar. 

By comparing the present figure (PI. XI, fig. 15) with that 
of Cuiex (CarroUia) paraplesia from Colombia (Ins. Ins. 
Mens., X, PI. V, fig. G, 1922), it will be seen that they are 
practically identical. It is probable that they are synonymous. 
Perhaps Euhonnea should not be separated subgenerically from 
Caitollia. The palpi of the male are short in the present species, 
longer than the proboscis in CarroUia proper. 

Cuiex (Aedinus) originator Gordon & Evans. 

The figure (PI. XI, fig. 18) is redrawn from that of Gordon 
& Evans (Ann. Trop. Med. & Par., xvi, .‘^24, 1922). The palpi 
of the male are short, and the species must be close to, if not 
the same as A'edwus a^nazonensis Lutz, the type of Aedinus. 

Cuiex (Aedinus) conservator Dyar & Knab. 

The clasper is bent at right-angles and is hairy without 
PI. X, fig. 2). The palpi of the male are short. 

Cuiex (Aedinus) bifoliatus Dyar. 

Similar to the preceding (PI. X. fig. 8), with greater develop- 
ment in detail of the divisions of the lobes of the side-piece. 
The pali)i of the male are short. 

Cuiex (Aedinus) corrigani Dyar & Knab. 

The clasper is less strongly bent and less hairy without (PI. 
X, fig. 1). The divi.sions of the lobe of side-piece are reduced. 
The jxilpi of the male are short. 

Cuiex (Aedinus) homoeopas Dyar & Ludlow. 

Agreeing in the structure of the clas]:)er with conservator and 
bifoliatus, the divisions of the lobe of side-piece remarkably 
developed (PI. X, fig, 1), but the palpi of the male exceed the 

Cuiex (Aedinus) restrictor Dyar & Knab. 

The clasper is still less strongly bent than in corrigani and 
the lobes of the side-piece are not unlike it (PI. X, fig. 7), but 
the palpi of the male are long, exceeding the protoscis. The 

190 iNSScuToR ivscitiM mnsfOMts 

shortening of the tna]e palpi is thus seen not to be parallel with 
^ hypopygial structures. 

Ctilez (Helcoporpa) menytea Dyar. 

The t 3 T)e of the subgenus is shown in the figure (PI. X, 
fig. 8). The ninth tergites are well developed, conical, setose. 
The palpi of the male exceed the proboscis. 

Culex (Helcoporpa) trifidua Dyar. 

There is no particular relationship in the structure of the 
clasper of this species with the preceding (PI. X, fig. 9), but 
it seems scarcely worth while to erect a subgenus upon it. The 
ninth tergites are completely undeveloped. The palpi of the 
male exceed the proboscis. 

Since the foregoing was written I have seen an article by 
Miss A. M. Evans (Ann. Trop. Med. & Par., xvii, 371’, 1983) 
in whidi she identifies as Aedinus amazonensis Lutz a male 
with short palpi which she finds to agree better with Lutz’s 
description than Culex originator does. This male is dose td 
Culex {CarrolUa) paraplesia Dyar. I think that Miss Evans' 
supposition is very plausible, and I will, temporarily at least, 
adopt it, with the following synonymy: 

Culex (Aedinus) amazonensis Lutz. 

Aedinus amasonensts Lutz, Imp. Med., Mar 35, 1905. 

Culex (Bubonnea) tapena Dyar, Ins. Ins. Mens., vii 150, 1919. 
Culex (Carrollia) paraplesia Dyar, Ins. Ins. Mens., x, 193, 1928. 
Culex hildebrandi Evans, Ann Trop. Med. & Par., xvii, 377, 1923. 

The differences noted by Miss Evans between her spedmen 
and my description of paraplesia are due to variation in die 
number of teeth of the tenth sternites or to some of them 
lieing concealed in the mount, while the ninth tergites were 
overlooked by me. They are correctly described under tapem. 

This identification of Aedinus invalidates the one used 
me in the foregoing. Aedinus will replace Eubonnea, while for 
the group called Aedinus by me, the new name AnoedU^KOrpa 
is proposed, with type conservator D. & K. 





(Coleoptera, Lampyridae) 

By H. S. barber 

Professor F. Campos R., of Guayaquil, has kindly submitted 
specimens of a large glow-worm found at three stations in 
Ecuador, viz., Angamarca, 3,000 meters altitude, Aloag, 2,920 
meters altitude, and Pifo, 2,588 meters altitude, representing, 
respectively, a female, a large well preserved larva, and a smaller 
poorly preserved larva. 

As the classification and identification of Lampyridae is based 
upon males, and for the present leaves us ignorant of the 
structures of the females and larvae of most genera, it has been 
very difficult to decide what generic name to use in recording 
the facts they offer. 

The species is so large and so strongly colored that its male 
must be a conspicuous form and should be expected to display 
the same type of coloration (black legs and disc of pronotum, 
the latter with yellow side margins) as in the female and larva. 
A search of the literature on Andean Lampyrids for described 
species to which these specimens should be assigned has been 
very unsatisfactory in results, but in the genus Phcrttolis a 
species having this coloration and collected at Belzapamba, 
Ecuador, has been described by Fyrnest Olivier (1907) under 
the name Phccnolis abditus} The adoption of this name for 
the specimens here described is very uncertain, because species 
of several genera in which only males are as yet known will 
undoubtedly be found inhabiting the same region and only the 
rearing of adults from larvae and observation on the mating of 
the adults can corroborate or disprove the determination here 

The larger larva was kept under observation for eight days 
by Prof. Campos, who received it from Aloag, 2,920 meters 

^The original description by Oliver (Genera Insectorum, fasc. 63, p. 10) is 
here freely translated* **Phaen 0 Us ahdxtns, n.sp. — Oblong, black; protborax angulate

altitude, in the Interandean region, about the end of May, 1922, 
and the following is freely translated from notes on its light 
which he was kind enough to supply. 

“The photogenic apparatus consists of two bodies protruding 
from the articulation between the penultimate and the ante- 
penultimate abdominal segments and occupying the sides of the 
latter. These organs emit a pale green phosphorescence of 
variable intensity ; thanks to the pale and membranous areas of 
the dorsal integument, the animal is able to show its light above 
as well as below.” 

There is preserved in the National Collection a large (50 mm. 
long, 14 mm. wide) dried Chilian lampyrid larva from the 
collection of E. C. Reed bearing the label “?Cladodes ater? 

At first sight it appears similar except in color to the one re- 
ceived from Ecuador but it differs greatly in the thickness and 
shape of side margins and in the apical tuberculation of the 
abdominal sternites as well as in the structure of seventh, eighth 
and ninth abdominal segments. It is very dark brown above 
and below but the thick side margins of all tergites and the 
upper margin of the pleurites form a narrow yellow border 
which is inairved around the posterior angles of the thoracic 
tergites, broadly interrupted at middle of sides of pronotum 
(though present on the ventral surface) and broadened ante- 
riorly into a pair of elongate oval yellow maculae at sides of 
front margin of pronotum. In all of its characters except 
those of its poorly preserved head it is more similar to the larva 
of Pleotomus than to other glow-worms known to me. In the 
absence of habitat data indicating the type of fauna in which 
this Chilian glow-worm was found I can only guess that it may 
be either the larva of the as yet undiscovered female of the 
genus Calyptocephalus, or that a very large Pleotomus-like male 
is yet to be discovered in Chili. 

The following description and accompanying figures of the 
female and large larva from Ecuador may contribute to a better 
understanding of the interesting problems presented by this

fovea at ventral apex of eye. Ocelli in a curved line. Stigmal 
moderately long. 

Male similar, funicle 1 shortest, quadrate, 2 equal chib 1, 
twice longer than wide, 3-4 longest. Club 3 conical ; 4 funicles, 
3 ring-joints, scape thicker, with a distinct, circular bulge 
beneath toward apex, the flagellar joints (save pedicel), with 
a long, spreading brush of silky hairs from base, smaller on 
distal two. 

Many specimens reared in late September, 1921, from large, 
reddish brown, velvety galls form the leaves of a forest bush, 
Wimnum, Queensland. 



Buonapartes^ new genus (Ceratoneurini). 

Genot)rpe: Ceratoncurella rufobasalis Girault. See original 

Buonapartea aeniceps, new species.

rectangular area from mouth to antennae; scape white, also 
apex of club slightly ; abdomen margined narrowly with black. 
Vertex, scutum pin-punctate, setose, latter with one black 
bristle caudo-laterad. Funicle 1 a half longer than wide, club 
with a long spicule, exceeding pedicel, latter exceeding funi- 
cle 1. Antennae below middle of face, scutellum 4 bristles, 
stigmal short, propodeum with a median carina which forks at 
base. Scutellum with lateral grooves only, scutum simple.

The first part under this general title was published in 1923 
(Ins. Ins. Mens., 11, 73-74). The new species described at 
this time were collected by Mr. T. R. Harris in Westland, and 
at Taumarunui in the North Island, and by Mr. Leon Curtis 
in Otago. Recently, Mr. Edwards has made the interesting 
discovery that all of the New Zealand crane-flies hitherto de- 
scribed as species of Trichocera should be referred to Para- 
cladura Brunetti, which was based upon a species from northern 
India. The genus is distinguished from Trichocera chiefly by 
the venation and the much abbreviated basitarsi. Besides the 
twelve sspecies now known from the Maorian subregion, Para- 
cladura includes four species from India and Formosa, and 
P. trichoptera (Osten Sacken) of western North America. 
The types of the new species described forthwith are pre- 
served in the writer’s collection through the kindness of the 
collectors, Messrs. Harris and Curtis. 

Paracladura harrisi, new species. 

Male . — Length about 3.7 mm. ; wing 4.4 mm. 

Rostrum, palpi, antennae and head dark brown. Mesonotum 
and pleura uniformly fuscous. Ilalteres pale, the knobs brown. 
Legs with the coxae yellowish brown; remainder of the legs 
pale brown with only the terminal tarsal segments a little 
darker. Wings subhyaline, the veins dark brown. Venation: 
5‘Ci ending opposite r, Sc^ at about midlength of Rs; /? 2 +a a 
little longer than the basal section of Ro ; r-m oblique, inserted 
at the fork of M; cell rst closed but m weak ; cell Mi about 
twice its petiole ; m-cu about two-thirds m. 

Abdomen dark brown throughout. Male hypopygium with 
the disti-styles moderately elongate, the mesal face near the 
basal third produced into an obtuse lobe which is entirely 
covered with microscopic setae as is the remainder of the mesal 
face. Each gonapophyse appearing as a flattened plate, the 

INSECUTOR INSCm^ menstruus 


caudal margin of which is produced into four or five con- 
spicuous spines, in the type there being five on the right side 
and four on the left ; beneath this apophyse and possibly a part 
of it, appears a complex structure which is densely set with 
appressed, feebly curved spines. 

Habitat, — New Zealand (South Island). 

Holotype, Rewanui, Paparoa Range, Westland, altitude 
600-800 feet, February 15, 1923 (T. R. Harris). 

Paracladiira harrisi is named in honor of the collector, Mr. 
Thomas R. Harris, to whom the writer is vastly indebted for 
invaluable collections of New Zealand crane-flies. It is most 
nearly related to the larger P, antipodeum (Mik.) of the 
Auckland Islands; the latter species differs in the obliteration 
of m-CM, and in the details of structure of the hypopygium, as 
the short, broad-based aedeagus, the different!}' constructed 
gonapophyses, and other details. 

Paracladura curtisi, new species. 

Male, — Length 2.6-2.8 mm. ; wing 3.4-3.() mm. 

Female. — Length 3-3.3 mm. ; wing 3.6-4.2 mm. 

Head and appendages dark brown. Mesonoluin dark brown, 
the lateral ends of the suture and the scutellum a little paler. 
Pleura brown. Halteres dark brown, only the extreme base of 
the stem paler. Legs dark brown throughout. Wings sub- 
hyaline, the veins dark brown. Macrotrichiae of veins long 
and conspicuous ; base of cell /.vt A with macrotrichiae. 
Venation : Sc^ ending some distance beyond r, Sc.^ before mid- 
length of Rs; r on /?2 a little more than its own length beyond 
the end of Rs: r-m just beyond the fork of M on M,+2 ; cell 
comparatively shallow, subequal to its petiole; cell Jst 
open by the atrophy of m; m-cu longer than r in the cJ, sub- 
equal in the 5, in alignment with the basal section of M\ ; 
cell ^nd A narrow. 

Abdomen dark brown, including the hypopygium. Male 
hypopygium of the same simple structure as P, macrotrichiata 
(Alexander) ; dististyles cylindrical, not at all produced on 
mesal face. Aedeagus and gonapophyses of very simple 
structure, the latter subtending and exceeding in length the 



former, appearing as slender, straight rods directed caudad 
and lying very close together along the median line of the 
body. Just beyond mid-length of the aedeagus, on either side, 
appears a small oval lobe, gently divergent, directed caudad. 
Ovipositor obscure yellow, the tip darker. 

Habitat, — New Zealand (South Island).

Paracladura curtisi is named in honor of the collector, Mr. 
Leon Curtis, who has collected much valuable material in the 
vicinity of Lake Wakatipu and on Stewart Island. It is most 
closely allied to the larger P, macrotrichiata (Alexander) from 
which it differs chiefly in the details of structure of the male 
hypopygium and in the venation, especially in the relatively 
shallow cell M^. The macrotrichiae are neither so numerous 
nor so extensively distributed as in macrotrichiata. In the 
latter species, the aedeagus extends far beyond the gonapophyses 
which are recurved and decussate across it. 

Paracladura decussata, new species. 

Male . — Length about 2.8 mm.; wing 3 mm. 

Cienerally similar to, and a close relative of, P, obtusicornis 
(Alexander), from which it differs chiefly in the structure of 
the male hypopygium. Head dark grey. Mesonotum shiny 
brown. Wings paler. Venation: Sc^ ending shortly beyond 
the fork of i? 24 s Scn about opposite one- fourth the length of 
Rs; m faint, l)eyond midlength of the petiole of cell Af, ; cell 
^nd A long and narrow. 

Male hypopygium with the dististyles relatively short, cylin- 
drical, feebly arcuated, entirely without lobes. Gonapophyses 
very conspicuous, appearing as powerful chitinized arms, di- 
rected caudad and thence mesad so as to be decussate across 
the genital chamber, the extreme tips suddenly narrowed and 
acute. In P. obtimcornis, besides the flattened, obtuse plates^ 
there are slender and very delicate, strongly curved horns di- 
rected cephalad and thence mesad. 



Habitat, — New Zealand (North Island). 

Holotype, Taumaninui, April 80, 1928 (T. R. Harris). 

Paracladura complicata, new species. 

Male, — Length about 8.2 mm. ; wing 8.7-8.8 mm. 

Female, — Length alx)ut 8.1 mm.; wing 1 mm. 

Generally similar to and a close ally of P. lobifera (Alex- 
ander), from which it differs in the darker coloration and the 
very distinct structure of the gonapophyses of the hypopygium. 

The general coloration is much darker than in lobifera but 
paler than in maori. The anterior part of the mesonotal 
praescutum is darker than the sclerites behind the suture. 
Wings pale brown, the veins darker. Venation : m far out on 
the petiole of cell usually less than its own length from 
the fork, due chiefly to the great depth of cell M^, 

Male hypopygium with the dististyle bearing a conspicuous, 
subbasal lobe on mesal face, as in lobifera, the apex of this 
lobe subacute and glabrous. The armature of the genital cham- 
ber is very intricate ; the lateral pair of plates bear one or two 
apical spines that are directed caudad, and two or three long 
spines on the outer or lateral edge that are directed laterad. 
A transverse slender bar lying across the chamber has the 
mesal end terminating in two powerful spines the mesal one 
small, the lateral one about twice as large, directed chiefly 
caudad ; lateral or outer ends of this bar extend laterad and 
terminate in numerous powerful curved chitinized hooks, the 
terminal ones largest, becoming smaller mesally and obsolete 
near midlength of each arm ; the arms of either side lie almost 
in a, straight line across the genital chamber. What seems to 
be the aedeagus is a massive, central plate, each lateral angle 
produced into a slender arm directed caudad, the tips strongly 
mesad, to produce a somewhat lyriform appearance. 

Habitat, — New Zealand (North Island).

The exclusion of Pollenia (P. rudis) from the family 
Calliphoridae, in my recent treatment of the group ^ resulted in 
a discussion with Mr. J. R. Malloch in which, after a consid- 
eration of the Old World species of Pollenia and allied genera, 
it was agreed that the scope of the family should be broadened 
to include this group. 

The revised characterization of the Calliphoridae is presented 
in the following key (by Malloch and Shannon). 

1. Hypopleura bare, or only with some fine hairs ( Scatophagidae, 

Anthomyidae, Muscidae) Muscaridae, 

Hypopleura with one or more vertical series of strong bristles 2. 

2. Postscutellum very pronounced* Tachinidae, Dexiidae* 

Postscutellum rudimentary or absent* 3. 

3. Species with arista minutely pubescent or bare, with prosternum and 

postalar declivity bare ; notopleurals 2 ; sternopleurals 1 :1 

(Wohlfartinae, Metopiinae) Sarcophagidae, in part. 

Species with arista hairy, often plumose, if almost bare the prosternum 
and postalar declivity hairy 4. 

4. Notopleurals 3 or 4 ; posthumeral never laterad of presutural ; sterno- 

pleurals usually 1 :1:1 ; hind coxae hairy behind, above base of hind 

femur Sarcophagidae, part, 

Notopleurals 2; sternopleurals 2:1 or 1:1, never 1:1:1; posthumeral 
usually laterad of presutural, sometimes in line with it, rarely 
absent, never mesad of presutural; hind coxae bare behind, above 
base of hind femur Calliphoridae, 

The above characterization holds good for these families for 
all parts of the world as far as our material at hand shows. 

The third subfamily of Calliphoridae, Polleninae, represented 
in North America by Pollenia and Melanodexia, may be dis- 
tinguished from the others as follows: Prostemum and pro- 
pleura bare ; sternopleurals 1 :1 ; jiarafacials hairy down to 
lowermost margin of eye. All the others have the prosternum 
and propleura hairy.

H. Jones, of Baton Rouge, specimens which appear to represent 
a new form, both generically and sj^ecifically. Professor Jones 
says: “On June 19, 1923, while splitting open stems of various 
wild grasses at Elm Park (West Feliciana Parish), Louisiana, 
with the idea of ascertaining whether Diatra-ea saccliaralis larvae 
were working in them, I found a large pink larva tunnelling in 
a rank-growing grass, specimens of which have since been 
determined by the Bureau of Plant Industry, through the kind- 
ness of Mr. J. E. Graf, as Briaufhus saccharoidcs. Inasmuch 
as Mr. T. E. Holloway of the Bureau of Entomology found a 
pink larva boring in sugar-cane in Mississippi (see ‘A New 
Sugar-Cane Borer,' by T. W. Harned, Quarterly ])ulletin of 
the State Plant Board of Mississippi, Vol. II, Nos. 1-2), it 
occurred to me that the one I had found might be the same 
s])ecies. After several attempts, seven moths have issued from 
a collection of larvae made by Messrs. C. E. Smith and W. G. 
Bradley at Elm Park on September 22, 1923. Pupae were 
found below the surface of the sand in the breeding jars, and 
field observations indicate that the larvae leave the grass-stalks 
in the field and enter the soil to pupate. 

“Mr. Bradley states that in breeding jars the larvae fed oh 
sections of corn and sugar-cane stalks; but where both were 
present, they preferred the sugar-cane.” 

Merapleon cosmion, new genus and species 

Eyes overhung by long hairs, in a group below and a little 


in front of the antennae, not equally distinct in all specimens. 
Tegulae not produced behind into a hood ; f rons smooth ; tibiae 
and tarsi unarmed; tongue well developed; tegulae not pro- 
duced into a dorsal ridge ; abdomen with dorsal crests on basal

In a recent paper ^ Dyar has considered Aedes abserraius 
F. and Y. and Aedes auroides Felt as identical species and 
placed them as synonyms of Aedes punctor Kirby. He has 
based this conclusion on the variable markings of the adult and 
the identical structures of the male genitalia. Furthermore, he 
has endeavored to show from rearings that the number of comb- 
scales in the larvae varies from 6 to 17 and the supposed larval 
differences indicated by Felt are thus bridged. He has omitted 
some characters which are very distinctive and I have con- 
sistently considered A. auroides Felt and A, abserratus F. & Y. 

* Ins. Ins. Mens., 7, 14-17, 1919. 



as distinct species. However, the descriptions by Felt of the 
larval and the adult characters of these species were not suffi- 
ciently detailed to warrant me in determining their exact status 
in relation to A, punctor Kirby. Edwards (1981)^ has indi- 
cated that punctor Kirby has a European form which he thinks 
may be considered as a variety {A, punctor var. meigenanus 
Dyar). Recently Wesenberg-Lund •* has published an account 
of A'edes (Ochlcrotatus) punctor Kirby based on the identi- 
fication of material by F. W. Edwards, of the British Museum. 

In order to determine the exact status of ahserratus F. & Y. 
and auroidcs Felt, I visited the New York State Museum and 
through the kindness of Dr. Felt and Dr. Leonard I was able 
to obtain the type material. On examination, my previous 
doubts were sustained and abserratus F. & Y. is distinct from 
A. auroidcs Felt. Acdcs auroidcs Felt is a synonym of A'edcs 
punctor Kirby, the larval and adult characters agreeing in every 
detail with published accounts and figures. 

Dyar^ (1981) in a study of the punctor group of Acdcs, 
describes a new species, Acdcs dysanor, based on males from 
Plattsburg, N. Y, The larva is unknown and apparently the 
author did not have females of this species. Dyar considers 
the larva to be close to punctor and perhaps indistinguishable. 

I have before me a long series of the larvae of A. abserratus 
F. & Y., also bred males and a few females. The genitalia of 
abserratus F. & Y. are identical with Dyar’s figures of 
A. dysanor. Felt’s material came from Elizabethtown, N. Y., 
not far from the place where Dyar’s dysanor was taken. The 
larvae are also distinctive and easily separable from those of 
punctor Kirby {auroidcs Felt). Dyar in his study of the larval 
characters of abserratus F. & Y. and auroidcs Felt is clearly in 
error in his conclusions. From examination of 41 larvae, the 
head-hairs in all cases are single (1 — 1) whereas in punctor

they are generally 8 — 8 or 1 — 8, though at times 1 — 1. 
Wesenberg-Lund figures for punctor Kirby 8 — 8 head-hairs. 
The comb scales in abserratus F. & Y. vary from 6 to 7, rarely 
8 (1 case in 40 counted) placed in a row. The number varies 
on each side running as 6/6, 5/6, 5/7, 6/6, 6/7, or 7/7. In 
punctor the comb scales vary from 11 to 15, the number on 
each side usually being different (9 counted), anc placed in 
two distinct rows. The most distinctive and easily recognized 
larval character is that of the dorsal brush of the anal s^^ent. 
In abserratus F. & Y. this consists of four long stiff hairs; 
in punctor Kirby it consists of two long stiff hairs and a pair 
of brushes, each consisting of 6-8 hairs arising from a comnum 

The synonymy of these two species should therefore stand 
as follows: 

ASdes punctor Kirby.

(Diptera, Culicidae) 


Professor Matheson’s separation of the larvae of Aedes 
punctor (auroides) and abserratus (dysanor) is interesting, 
but the characters are not so sharp as he indicates. By con- 
sulting my table (Ins. Ins. Mens., vii, 16, 1939) it will be 
seen that the comb-scales continuously grade from 6 to 17, while 
the head-hairs are indiscriminately single or double. Applying 
the character of the hairs of the anal segment, it results that 
the first two entries on my table (C6 and B39) are abserratus 
and all 'the rest punctor. The male C5 was mounted and showed 
typical dysanor genitalia. Therefore Matheson’s statement of 



the number of comb-scales in punctor should read 8 to 17, 
while the character of the head-hairs will have to be abandoned 
as diagnostic. 

To complete the synonymy, centrotus H., D. & K. should 
presumably be added to abserratus F. & Y. The types came 
from White River, Ontario, where my own collecting was 
done, and the isolations C5 and B39 are evidently larvae of 
this very form. 

In the larva of the European form {meigcnanus), which I 
have from England by the kindness of Mr. F. W. Edwards, the 
tuft of the anal segment is as in punctor, a long hair and a 
tuft on each side; comb-scales about 12 in a narrow patch; 
head hairs double or in threes. 

The western American forms aboriginis, cycloccrculus, leu- 
conotips and hexodontu^ all have the anal hairs as in punctor, 
and thus in this respect abserratus ( centrotus — dysanor) is 
unique, even as the male genitalia are unique. 

Concerning the two names of Walker, I have referred them 
to punctor on information furnished by Mr. Edwards (Ins. 
Itis. Mens., viii, 8, 1920). In respect to the present differentia- 
tion, however, this is not final. 

Concerning iniplacabilis, Edwards says: “Is almost certainly 
the same as punctor as identified by you.’* In another letter: 
“Mesonotum apparently all light brown, but a large pin is 
stuck right through the middle.” The specimen is a female 
from Martin Fall, Ontario. This can be nothing else than 
abserratus, assuming that it belongs to the punctor group at all. 
I would make the reference definite. 

Concerning provocans, Edwards says: ‘Ts quite unrecog- 
nizable, but might be punctor.*' Also: “There are two speci- 
mens, of which the male is probably the type ; the female may 
not belong. ^ perhaps = impiger, but the white scales look 
rather broader. Tip of abdomen is missing.” Since the abdo- 
men is broken in the male type, no positive determination can 
be had from the genitalia. The white scales mentioned by 
Edwards are presumably those left at the sides of the meso- 
notum, which suggests punctor rather than abserratus. The 


name may therefore remain where it is, giving the following 
synonymy : 

Aedes punctor Kirby. 

Ctilex punctor Kirby. 

Culex provocans Walker. 

Culiceha auroides Felt. 

ASdes implacabilis Walker. 

Culex implacabilis Walker. 

Culex abserratus Felt & Young. 

Aedes centrotus Howard, D3rar & Knab. 

A 'edes dysanor Dyar, 




In March and April, Helomyzids are very common in the 
Cranbrook District of British Columbia. On May 5, 1919, 
I took a female supposed to be Lcria serrata, but which had 
two very strong vibrissae and four stemopleural bristles. No 
other differences were noticeable, and the specimen was con- 
sidered a freak. From March to May I took perhaps two 
thousand Helomyzids, containing a large number of serrata, 
and in going over them, one proved to be a male, matching the 
above-mentioned female. In coloration and size they are exact 
duplicates of Lcria serrata. The male is easily separated by 
the very short hind tarsus and the distinct hyjxjpygium; the 
female is much more difficult of separation, unless we rely 
entirely on the four stemopleural bristles; otherwise we have 
left only the three or four rows of hairs below the vibrissae, 
where in serrata there is only one. 

Lena serrataria, new species. 

Foremost fronto-orbital about equal to the hind; four or 
five pairs of prosternal bristles; four dorso-centrals ; one 
humeral Thorax gray-black, abdomen red-yellow. 



Male. Two long strong vibrissae (serrata has one median 
and one short) ; three rows of hairs below them (serrata has 
one). This makes the space to the eye very small. Three 
strong sternopleural bristles (serrata has one). Hind tarsus I 
very short, about half the length of the second; hind femora 
swollen. Hypopygium distinct, very similar to that of Leria 
latens Aldr. 

Female. Very similar to serrata excepting the longer vi- 
brissae, with the three rows of hairs below, narrower gena, three 
sternopleural bristles; hind femora not swollen; hind tarsi I 
and II about equal (in serrata 1 longer than II). Postnotum 
with a distinct central ridge, less pronounced than in the male. 

The male tarsi, sternopleural bristles and hypopygium show 
it as a close ally of latens Aldr. 

In April, 1923, I collected in the south end of the Okanagan 
Valley, British Columbia, and secured a female. Also, on 
Mount Apex, at an altitude of 1,000 feet. I took a male and 
four females. 

Holotype, male. Mount Apex, B. C., July, 1923; allotype, 
female, Okanagan Valley, B. C., April, 1923, in the Canadian 
National Collection ; male and female paratyj^es, Cranbrook, 
B. C., May, in the author's collection. 

Amoebaleria perplexus, new species. 

Male. Foremost fronto-orbital about three-fourths of the 
hind one; one pair of prosternals; four dorso-centrals, one 
humeral bristle. Entire head, thorax, pleura, legs and hypo- 
pygium reddish yellow or brown ; tarsi darker ; abdomen 
blackish brown. 

One vibrissa rather long and fine; three rows of oral hairs 
below. Front and antennae red-yellow ; arista long, with 
microscopic pubescence. Dorsum of thorax with fine long 
hair; a dark red-yellow vitta through the roots of the dorso- 
centrals; another not reaching the suture beyond it. Dorso- 
centrals very fine ; scutellum with four bristles ; pleural bristles, 
one propleural, one sternopleural; mesopleura bare, except a 
square patch of long fine hairs below the disk; pteropleura 


INSKCUTOR INSCm^ menstruus 

bare; sternopleura covered with long fine hairs, longer and 
stronger between the coxae, where only I is bristly. No distinct 
abdominal bristles, but entirely covered with long fine hairs; 
legs the same. Wings dark hyaline basally; tip of scutella

1921, in author's collection ; paratype, male. Mount Apex, 7,000 
feet, Headly, B, C., in the Canadian National Collection. 

The male hypopygium, from a fresh extended specimen, was 
compared with that of A, scutellata, mounted on a slide, prov- 
ing the entire distinctness of the two species. Perplexus bears 
the same relationship to scutellata that gigas does to fratema. 

In examining the male hypopygia of a sefies of Anorostoma 
before me, it appears that two other forms are represented 
besides currant recently described by me. These forms may 
not be distinct species, but may represent geographical races. 
Until such time as the male hypopygium of Loew s type of 
A, margimta is exposed, we cannot state definitely just which 
is Loew’s species. The following descriptions are presented 
subject to that correction. 

Anorostoma coloradensis, new species. 

Male. Head pale red-yellow, front redder, antennae pale 
red-yellow; arista shorter than the eye; one vibrissa; a single 
row of hairs below, well separated from the oral margin ; two 
fronto-orbitals, the foremost about half the length of the hind. 
Thoracic dorsum yellow-brown, dark brown spots at the roots 
of the hairs and bristles, four dorso-centrals and scant short 
black hair. Pleura yellow-brown, a darker brown stripe from 
the humerus across the mesopleura to the top two bristles. 
Propleura, one bristle; mesopleura one, and above it a short 
bristly hair, below it a longer bristly hair, in a row along the 
hind edge. Two coarse hairs below the disk. Pteropleura 
bare. The suture between the meso- and pteropleura joins the 
sternopleura almost at right angles and if continued would pass 
well in front of the bristle. Sternopleura with one bristle near 
the lop hind corner, with a few scattered hairs running directly 



down the center to many bristly hairs below the coxae. Abdo- 
men yellow-brown, black haired. Wings hyaline, small cross- 
vein slightly infuscated, veins yellow to brown. Legs pale 
red-yellow, fore femora with a dorsal and a ventral row of 
four or five bristly hairs, the rest rather scantily haired. Mid- 
femora, one longer bristly hair on the outside about the apical 
third; a row of bristly hairs on the lowest inner edge. Hind 
femora with four strong bristly hairs on the apical third near 
the outer edge. Claws brown, slightly black tipped, and about 
as long as their tarsal joint; tarsus 5 hardly as long as 3 and 
4 together. 

Female. In general exactly as the male, but the abdomen is 
blacker, the top mesopleural hair is longer than the third, there 
is an additional bristly hair in front of the sternopleural bristle, 
fore femora with two rows of bristly hairs on the upper edge, 
only two bristly hairs on the hind femora ; tarsi longer and nar- 
rower, claws shorter.

Allotype, female, Colorado, labeled 2030 (through Dr. C. W. 

Paratype, male, Colorado, labeled 1389, received from the 
State Natural History Survey of Illinois, Urbana, and returned

Anorostoma jersei, new species. 

Male. The description of the male of A. coloradensis will 
suffice for this also, and we give for this species a comparative 
description. The insect is larger. A much less sloping front 
from the oral margin to the antennal base ; head deeper , f ronto- 
orbitals wider apart ; thoratic dorsum more hairy ; fore femora . 
with stronger bristly hairs, and an additional smaller row near 
the top edge ; mid femora with the bristly hair stronger. Both 
hind legs missing. Claws brown with the tips black to nearly 
half way, and long ; tarsus 6 appears to equal 3 and 4 together. 
Stemopleura with a single row of hairs down the center ; meso- 
and pteropleural suture sloping back, joining the stemopleura

in a direct line to the bristle; mid tibial spurs larger and 
stronger. Hypopygium on a slide. 

Monotype, male, Manuniuskin, New Jersey, May r>, ]903 
(through Dr. J. M. Aldrich). 

Following is proix)sed a new genus and also a key, which 
will place the genus Lutomyia described by Dr. Aldrich last 
October. These two genera seem to occupy the missing links, 
as it were, to two distinct branches of development. The im- 
portance of prosternal bristles seems further increased as being 
of the most modem development, though perhaps of no generic 
value. Leria incrs Meig. appears the most primitive form of 
the genus. The genus Lutomyia seems the direct route to 
Leria, and Viatica to Eccoptomcra, 

For those who wish to place these genera in my key pub- 
lished in this magazine (ix, nos. 7-9, page 120, 1921), we start 
at section 6 and reconstruct it. 

6. Mid femora with one to three rows of stout spines on the outer side; 

spinulae long and stout 6c. 

Mid femora with no such spines, setulae usually small 6a. 

6a. Mid tibia with a very short preapical bristle; a single extra long 
apical spur, much longer than the apical bristle, 

Thephrochlamys Loew. 

Mid tibia with several longish apical spurs .6b. 

6b. Mid tibia with one preapical bristle; the small cross-vein usuall> 
below the tip of R, I.; usually two pairs of sculellar bristles, 

\JorpholerM Garrett. 

Mid tibia with two or three preapical bristles; tip of R. I. far 
beyond the small cross vein ; usually three or four pairs of scutel- 
lar bristles, 

Crymobia Loew, Anorostomoides Malloch, Barbatus Garrett. 
6c. Small cross-vein over the basal fifth of the discal cell ; veins Sc-R. L 

very short, R 3+4 .shorter than usual Lutomyia Aldrich 

Veins about normal; mid tibial apical spurs long and numerous; 
mid tarsus I with four or five pairs of apical setulae, one very 
long pair, those of tarsus II not so prominent; head deep, oral 
margin far beyond the root of vibrissae Viatica new genus. 

Lutomyia distincta, new species. 

A striking general resemblance to Leria serrata. Foremost 
ftonto-orbital about half the length of the hind one; four dorso- 
centrals, one humeral. 



Head, occiput gray, front dark orange-yellow, face dark red- 
yellow, antennae very dark red-yellow, third joint round ; arista 
(somewhat blunt-tipped and thus may be broken, though of 
even length in both) black, microscopically pubescent. One long 
vibrissa and one row of long black hairs below it. Bare gena 
about half the depth of the eye. Oral cavity sloping up toward 
the antennae ( ?the original step to genus Anorostoma), thus 
shortening the space below them; oral margin chitinized all 
around, and well above the root of the vibrissae ; thorax, dorsum 
gray-black, with a brown shade, thickly covered with short 
thick black hair ; scutellum, four bristles ; pleura gray-black, one 
propleural bristle, mesopleura bare except four hairs below the 
disk ; pteropleura bare ; sternopleura, one strong ])ristle near the 
top hind corner, then one median bristle, then two short bristly 
hairs in a row before it, the rest bare to the level of the coxae, 
between which are many long hairs and bristles. Halteres 

Wing spines rather short. Veins Sc, Rl, R2-t-3, all shorter 
than usual. Sc joins C nearly above but a little beyond the 
small cross-vein ; Rl joins C less than half way over the discal 
cell, but more than its basal third. R2~f-3 parallels Rl, enter- 
ing C in its third quarter at a jK)int just beyond the large cross- 
vein. R4+5 not quite reaching the extreme apex of the wing, 
thus lying almost directly alx)ve the tip of M. Small cross-vein 
joins the discal cell at less than the length of the first basal, or 
about one-sixth of the discal ; large cross-vein normal. 

Wings gray hyaline and in lights slightly yellowish. 

Abdomen, red-yellow, with short thick black hairs and apical 
bristles. Legs red-yellow, fore femora infuscate outside, fore 
tarsi depressed cordate, in 2, 3, j, the 5th more linear; tarsi 
of the other legs all linear, especially of the mid legs. Mid 
femora with a row of 10 or 11 thick spiny bristles down the 
middle. Mid tibia with 8 apical spurs; mid tarsus 1 with two 
dorsal and two ventral pairs of apical spines, the others with 
only one set, those of the hind tarsi not conspicuous. 

Monotype, female, Bentleys Siding, Rushmere, Windermere, 
British Columbia, November 15, 1922 (C. Garrett). 


insecutor insciti^ menstruus 

Rushmere is about 11 miles south of Windermere, at the foot 
of the lake. The large eye, spines on the femora, and shape of 
the fore tarsi seem to denote the origin of Lena iners, Meig. ; 
on the other hand the mid leg is far more like that of Bccop- 
tomera simplex, which also has the small cross vein slightly 
before the middle of the discal cell. 

Viatica, new genus. 

Two fronto-orbitals, the foremost from about a half to 
three-fourths of the hind one. No prostemal bristles. Mid 
tibia with one preapical bristle. Head deep, eye large; mid 
femora with irregular rows of spines on the outside. Genotype, 
the following. 

Viatica spinosus, new species. 

Head deep, viewed from the front dee])er than broad. Fore- 
most fronto-orbilal just less than half the hind one. Eye 
perpendicularly oval, its height about equal to the length of the 
head. C)ne strong vibrissa, one row of hairs below, toj) of the 
oral margin very much higher than the root of the vibrissae 
and chitinized all round ; oral margin to antennal roots straight. 
Head and antennae red-yellow, both third joints missing. 
Thorax, dorsum of mixed colors, general look black-gray, with 
the edges of humeri and scutellum red-yellow ; four very strong 
dorso-centrals with slight dark brown six)ts at their roots and 
much short thick black hair. C)ne humeral bristle, two pairs 
of scutellar; pleura mixed black-gray or red-yellow, one pro- 
pleural bristle; mesopleura bare except two hairs below the 
disk, pteropleura bare, sternopleura with scars of two bristles 
(rubbed off) ; two or three hairs in front of them, the rest 
bare except l>etween the coxae where there are two hairs and 
comparatively few bristles. TIalteres red-yellow ; abdomen red- 
yellow, sparingly haired, the segments with only median apical 
bristles. Legs red-yellow sparingly haired; fore femora with 
two dorsal and ventral rows of bristly hairs ; mid femora with 
3^ rows of thick spines on the outside, the lowest row on the 
l)asal half, the longest on the apical half down the center ; top 
row on the apical half. Mid tibia with nine apical spurs all 



long but uneven ; tarsus I with six and tarsus II with four pairs 
of setulae, a very long strong one inside the apex of tarsus I. 
All tarsi linear. Wings hyaline, costal spines of two sizes, 
much as in pectinata, but all rather short : veins yellow-brown, 
Sc and R and R2+3 rather short. Small cross vein slightly 
beyond the middle of the discal cell. 

Monotype, female, Yosemite Valley, California, May 22, 
1908. The type will be in the collection of the Academy of 
Natural Sciences, Philadelphia. 

The above insect has been compared with a female of Ecco- 
ptomera simplex from its tyi)e locality. In a recent letter, Dr. 
Aldrich informs me that the type of Eccoptomcra amcricana he 
considers identical with simplex Coq., which thus has priority. 

In a numl^er of details the genus Viatica is much closer to 
Eccoptomcra than it is to the Lcria group, and seems to spring 
directly from Pseudoleria ( pectinata), 

Barbastoma barbatus Garrett. 

Having compared the genus Barbastoma with AnorostO’ 
moides, it now seems advisable to give a description of the 
female Barbastoma barbatus, which at the time of describing 
I did not associate with it, but had temporarily placed it as 
possible Anorostomoidci petersom Mall. Through the kindness 
of Eh-. Forbes and Dr. C. P. Alexander, 1 was able to examine 
the type of petersom, my female proving distinct Upon re- 
ferring to the data I found that two specimens were captured 
near the same time and place as the type B. barbatus, seven 
days later. This fall I decided to try and obtain more, and was 
close to the same spot (perhaps 20 miles) and only succeeded 
in obtaining another female. But all things point to it being 
the female discussed. At the time of describing barbatus, I was 
struck by the l)eard. The females do not have any. The front 
fronto-orbital in the female is also slightly shorter than in the 
male, which then throws it into the second division of my key, 
where it runs to Anorostomoides. At the present time 1 have 
not fully decided if it should become a synonym of it. This 
may depend on whether Anorostomoides becomes a synonym 



of Crymobia, which in a recent letter Dr. Aldrich informs me 
that he and Dr. Mallocn think it should be. 

Female. Head brownish, front red-orange, face red-yellow; 
one vibrissa, two rows of black hairs below it to the lower 
corner of the cheek, the long pale hairs of the male absent. 
Thorax, dorsum olive brown, six or seven dorso-centrals of 
different sizes, abdomen and pleura concolorous with the thorax. 
Fore tarsus 1 with no apical hook-like claw. Wing, the bump 
over the Sc less prominent, tip of Rl far beyond the small 
cross-vein, which is directly below the tip of Sc and about the 
center of the discal cell. 

Notes on the male. This summer I found specimens of the 
male in the collection of the museum at Banff, All)erta, taken 
there, and can now say that it has six to eight dorso-centrals, 
variable in size. The color is the same as the female. When 
examining the type of barbatus, Dr. Aldrich sprung the fore 
leg and showed up the distinct ajncal claw-like hook at the tip 
of tarsus I which I had not observed. This is one of the generic 
characters of Crymobia Loew.

Plate I 


A numljer of features of the wings of Diptera, aside from 
the venation, have become of increasing imjx)rtance in morpho- 
logical and systematic work, and for this reason particular 
attention should be called to them. 

Epaui^et (== tcgula — Snodgrass, Comstock, Crampton) 
•Lowne & Parker. A small, usually hairy or bristly, more or 
less chitinized pad at base of costal vein. Considered a part 



of the thoracic int^ument but formed as a scale-like pad over- 
lapping the base of the costal, or more specifically, the basicosta. 
The bareness, pilosity or bristling, as well as the color, of the 
epaulet frequently offers good diagnostic characters in such 
groups as Tabanidae, Syrphidae and Muscoids. It is rudi- 
mentary or absent in a number of families, particularly in the 

Basicosta (— subtegula; subepaulet — Parker). A more or 
less spear-head shaped structure immediately beyond the 
epaulet, i. e., between the epaulet and the basal end of costa. 
It api>ears to be morphologically a part of the costa and for 
this reason is given a name independent of the epaulet. At 
times it stands out as an isolated structure. The vestiture and 
color of the basicosta offer good characters between species in 
a number of families; e. g., Lncilia cacsar and sylvarum have 
the basicosta black but scricata and pilatci have it lemon yellow. 

Subcostal Sclerite. A more or less triangular structure 
on the lower side of the wing, probably produced by a general 
fusion of the bases of the upper veins. In Tabanus the outer 
margin is developed as a thin, plate-like expansion extending 
between the basicosta and base of the first vein which it partly 
overlaps. In the Muscoids it may bear small setae. In the 
Calliphoridae the genera with the stem vein ciliated have the 
axillary sclerite setose; those forms with bare stem vein have 
it merely pubescent. The color is sometimes of use. 

Stem Vein. The radius, or first longitudinal vein, is divisi- 
ble into two sections, the basal section, or stem vein, which is 
separated from the rest of the first vein by a suture, usually 
easily apparent from the upper side. These two sections seem 
to be different in character. Pandelle discovered that the basal 
section only is ciliated in certain Muscoid genera and to dis- 
tinguish it from the rest of the vein he called it the “souche 
commune*’ = stem vein, in which he is followed by Aldrich. 
On the other hand, the Tabanidae have the stem vein nude but 
the outer section of the first vein is setulose. 

Setose Veins. In many of the Orthorrhaphous families 
certain veins bear distinct setae of various sizes while in many 



of the higher flies certain veins or sections of veins are setose. 
In the Tabanidae the setae are so characteristic of certain veins 
that the genera can to some extent be keyed on this character. 
The veins which may be setulose are the costa, auxiliary vein, 
first vein and the basal section of the fifth vein, i. e., the vein 
bounding the posterior side of the second basal cell. The 
setulae on the other veins are always as well developed as 
those on the costa. The presence or absence of setulae on the 
auxiliary vein divides the family into two nearly equal groups 
of genera. The Tabanidae in the National Museum collection 
were examined and it was found that the genera with bare 
auxiliary vein belong to the group possessing hind tibial spurs, 
while those with the auxiliary vein setose lack the hind tibial 
spurs. Furthermore, the following genera have the basal section 
of the fifth vein setose Pangonia (sparse), Mycteromyia, 
Goniops, Apatolcstes (sparse), Dtachlorus (three species, ferru- 
gatus, scutellata, curvipes), were examined and all have the 
setulae extending beyond the basal section of the fifth vein. 
Pelecorhynchus darmni Ricardo, Chilean species, has the 
setulae reduced more than all the others, they being nearly 
absent on the first vein and the outer margin of the costal vein 
is bare. Moreover, this species has a distinct groove in the 
upper side of the base of the costa. Even a casual observation 
will show that many Nematocerous forms have similar setulae 
on certain veins. 

Squamal Fringe of Ciua. This is a well-known character 
but its presence or absence in various groups as well as its 
difference in appearance can be u.sed to advantage in many cases 
where it has not been noticed.

> The prothorax of mosquitoes although minute has consid- 
erable taxonomic value, for which reason it seems justifiable to 
call attention to an error in terms applicable to this part of 
the body. Dr. G. C. Crampton recently called the writer’s at- 
tention to the fact that the so-called "proepimeron” of the 
mosquitoes is in reality a pronotal structure. Inasmuch as this 
sclerite figures prominently in taxonomic work on account of 
the "proepimeral” bristles that it bears, a study of the phylo- 
genetic history of this plate was made which substantiates Dr. 
Crampton’s assertion of its pronotal origin 

Although its presence in much the same form can be demon- 
strated in groups more primitive than the Diptera, a series of 
three dipterous specimens will indicate its undoubted pronotal 

In the tipulid figured (PI. II, Figs 1, 2) it will be noted 
that the pronotum has become secondarily divided transversely 
into two sclerites — a posterior (pn) and an interior pronotum 
(an) which Snodgrass (Proc. U S N M , vol. 36, pp. r)ll-596) 
has called the scutum and scutellum of the pronotum. In other 
tipulids the division of the pronotum into an anterior and 
posterior portion is marked merely by a depression and the 
intervening membranous connection is missing, although the 
lateral extensions remain the same and both sections arch the 
dorsum in a true notal fashion. 

In the family Dixidae, which is considered by some authori- 
ties as a subfamily of Culicidae, we find an intermediate step 
between the dorsal position of the sclerite in question in Tipu- 
lidae and the lateral position of Culicidae. In this group (PI. 
II, Figs. 3, 4) the anterior pronotum (an) has lost the broad, 
strap-like appearance found in the Tipulidae and is compressed 
into two lobe-like structures narrowly connected medianly. The 
posterior pronotum tpn) has bwn pressed laterally and pos- 
teriorly to a humeral position encroaching on the mesonotum (n) 
but with the lateral parts united medianly under the peak of 
the nwsonotum. 



In the Culicidae the pronotum has become more widely di- 
vided dorsally (PI. H, Pigs. 5, 6). The anterior pronotum (an) 
is represented by the prothoracic lobes which arc distinctly 
lateral in most genera, although they are sometimes approximate 
or connected dorsally by a narrow chitinous strip. The posterior 
pronotum (pn), although occupying the same relative position 
as noted for Diva, has lost its median dorsal connections and 
has become frankly lateral, a fact that caused Snodgrass in the 
Monograph of Howard, Dyar and Knab to call it the pro- 
epimeron despite its definite homology with the sclerite of the 
pronotum which he had previously called the scutellum of the 

The true proepimeron (ep) in all of these cases cited occurs 
in its normal position caudad to the proepisternum (es). 

The terms '‘scutum” and “scutellum'' as applied to the homol- 
ogous sclerites in 'Pipulidae are inapplicable even in the Tipu- 
lidae as the line of division separates parts that are not homol- 
ogous with the true scutum and scutellum of the mesonotum. 
The term “pronotal lol>es" as applied to the homolog of the 
posterior pronotum in Tabanidae is an expressive and correct 
term but is inapplicable in the Culicidae on account of the 
confusion that would arise between these lobes and the anterior 
pronotum which is commonly called the “prothoracic lobes." 
“Humeral lobes" would be applicable to the sclerites of the 
|X)sterior pronotum in Culicidae and Dixidae, although it car- 
ries no implication of pronotal origin and it would have little 
significance in the Tipulidae where the bands extend across the 
dorsum. The term “postnotum” is synonymous with "post- 
scutellum'’ and consequently inapplicable. It appears, there- 
fore, that to be correct and at the same time appropriate we 
must revert to the cumbersome name of ix)sterior pronotum or 
IX)Sterior pronotal plates.

(Dipiera, Culicidae) 


I have shown in discussing the mosquitoes of the Yellow- 
stone National Park that the Canadian fauna follows the 
mountain crests into Wyoming. It extends also into Colorado 
along the 7,000 foot level, not much below that. Collections 
were made at Grand Lake in the early spring of 1923, and I 
was fortunate enough to arrive before the Public Health Service 
had completed its extermination work. These mountain mos- 
quitoes are so easy to destroy that it seems almost like taking 
an undue advantage of nature. Certainly the able and sharp- 
eyed man who had been employed to spread oil on the pools 
left little enough for a late collector. 

The existence of the Canadian fauna in the higher altitudes 
of Colorado has not been fully realized. Professor T. D. A. 
Cockerell published a list of the moscjuitoes of the State (Journ. 
Econ. Ent., xi, 195-200, 1918) in which only two or three species 
of the Canadian fauna are included. For comparison, this list 
is reproduced, Wyoming localities omitted, and some of the 
determinations commented upon. 

Anopheles quadrimaciilatus Say. Only from the western 
lx)rder of the State. The determination is uncertain until 
verified by a male. The specimens mentioned from Hotchkiss 
and Delta in the Monograph (Howard, Dyar & Knab, Mosq. 
No. & Cent. Am. & W. 1., iv, 1032, 1917 ) cannot now be found. 

Culcx iarsalis Coquillett. “Common up to about 6,000 feet.” 

Culex pipiens Linnaeus, “Recorded from Denver by Tucker 
in 1907.” The identification was wrong. In the Monograph a 
second error was made, the specimen having been transferred 
to Culiseta inornatus (Howard, Dyar & Knab, Mosq. No. & 
Cent. Am. & W. I., iii, 493, 1916). The specimen still exists 
in the National Museum collection, being a male of A'edes 
trivittatus Coq., a species not otherwise in CockereU’s list. It 
is an inhabitant of flood-pools along rivers at low altitudes. 

Theohaldia inornata Williston. Said to range from 5,000 to 



9,800 feet, but I think some confusion has occurred, as the 
material collected by me at the higher levels comprised only 
Culiseta impaticns Walk, as specified below. 

Theobaldia incidens Thomson. Recorded only from the west- 
ern part of the State. 

Acdes puHatus Coquillett {acrophilus Dyar). ‘Tt is a moun- 
tain species in Colorado, belonging especially to the Canadian 

Acdes aldrichi Dyar & Knab. Recorded from Boulder. This 
may be the form of idahoensis with dark veins referred to 
below. The species cannot be recorded from Colorado without 
further confirmation. 

Acdes curriei Coquillett. “Common at lower altitudes in 

Aedes idahoensis Theobald. “In Colorado, idahoensis is of 
the Transition and Canadian Zones.” 

Acdes mimesis Dyar. “A species of the higher mountains.” 
This is the western form of fitchii. 

Aedes nigromaculis Ludlow. “A species of the plains.” 

Acdes sansoni Dyar & Knab. The types of sansoni were a 
mixture of fitchii (mimesis) and excrucians, restricted by me 
to the latter. Both these species occur in the Canadian Zone as 
specified below and are probably mixed under sansoni. See 
also hewitti and mutatus. 

Acdes stimulans Walker. Not known to occur in Colorado. 
The record should be cancelled. 

Aedes vexans Meigen. “Very common at lower levels.” 

The following is a record of the species collected at Grand 
Lake and vicinity, 8,000 to 10,000 feet, to which is added 
Cockerell’s records not otherwise included, making a list of 
the known mosquitoes of Colorado. 

As compared with my captures in Wyoming (Ins, Ins, Mens., 
xi, 36~4G, 1923), five species are omitted, Acdes hirsuteron, 
spencerii, canadensis, diantaeus and cacothius, while three are 
added from Cockerell’s, Anopheles quadrimaculatus, Aedes 
trivittatus and Culiseta incidens, and two from my captures, 
Culiseta impatiens and Aedes riparius. 



Anopheles quadrimaculatns Say. 

Recorded from western Colorado. The species actually pres- 
ent may be maculipennis Meig., males being necessary to decide. 

Aedes fitchii mimesis Dyar. 

The larvae were found at Grand Lake, breeding in grassy 
marshes and in a small pond near Columbine Lake where they 
were scattered about in the middle of the shallow water. The 
first adults appeared June 11. The commonest of the ring- 
legged Aedes, 

The name mimesis is based on males from Drummond, Mon- 
tana. At the time, larvae of excrucwns from Kaslo, British 
Columbia, were wrongly associated (Ins. Ins. Mens., v, 116, 
1917). Later (Ins. Ins. Mens., viii, 15, 1920), I showed the 
development of the form westward, and associated the correct 
larva from Dawson, Yukon Territory. Finally (Ins. Ins. 
Mens., viii, 117, 1920), I associated mimesis as the western 
race of fitchii. Relying on the supposed weakness of the basal 
hypopygial spine in mimesis, I stated (Ins. Ins. Mens., xi, 40, 
1923) that adults from the Yellowstone National Park were 
true fitchii and not the form mimesis. The larvae were not at 
hand in that instance or it would have been evident that the 
form was mimesis The weakening of the spine in the western 
form is slight and not diagnostic. The lengthening of the 
claspette filament is a more reliable character; but the male 
genitalic differences between fitchii and mimesis are weak at 

Aedes riparius Dyar & Knab. 

Larvae agreeing with those of this species were found in a 
pool near Columbine Lake, June 2, 1923, but no adults were 
secured. They occurred with excrucians and others. I think 
there can be no doubt of the identification of this characteristic 

Aedes increpitus hewitti Hearle. 

This is the mutatus of my Yellowstone P!ark list and was not 
met with by me in Colorado. It occurs, however, being re- 



corded by Cockerell under **sansoni' as “Here also a small 
variety which looks distinct.” His locality was Crystal River 
near Red Stone. Specimens of this form are in the National 
Museum as follows: 

CoWRAix): Crystal River above Red Stone, July 27, 1917 (P. 

Florissant, July 4, (T. D. A. Cockerell). 

Florissant, June 2(), 1907 (S. A. Rohwer). 

Aedes increpitus mutatus Dyar. 

The larger form inhabiting the river valleys in dry plains. 
Cow)RADo: Modern (between Denver and Boulder), May 28, 
(T. D. A. Cockerell). 

Mr. Hearle has lately proposed (Can. Ent., Iv, 205, 1923) to 
unite hemitti and mutatus on the ground of absence of genitalic 
differences. I can detect no larval differences either; but 
hetmtti is uniformly smaller, and inhabits the upper river valleys 
in the mountains. In the present paper the forms are separated 
in this sense. Probably the two will be found to run together 
at intermediate levels; but there seems to be an incipient dif- 
ferentiation here, for which the two names may be used if 

Aedes excrucians Walker. 

Found in the Grand Lake region, almost as common as 
mimesis, A typical male was mounted, collected above the East 
Inlet, June 21, 1J123, and larvae were found in a pool near 
Columbine Lake, June 2, 1023. 

Aedes punctor Kirby. 

Not uncommon about Grand Lake, the male hypopygium and 
larvae normal. The species occurred also at Poudre Lakes, 
10,740 feet, breeding in pools in a sloping meadow recently 
vacated by the snow banks and still overrun with water from 
the melting snow. With it were associated larvae of Aedes 
pullatus, whose occurrence is normal in such a situation. The 
situation is distinctly unusual for punctor; but no differences 
are observable in male structures or larvae. The adults have 



the mesonotum entirely brown, as in punctodes from northern 
Alaska. Male mounted, Grand Lake, June 19, 1923; twelve 
specimens from Poudre Lakes, July 4-8, 1923. 

Aedes idahoenais Theobald. 

Found breeding in pools in a grassy meadow at Grand Lake 
early in the season with cataphylla and impiger. The larvae 
agree with my description (Ins. Ins. Mens., v, 187, 1917), but 
the adults have the second and fourth veins only slightly paler 
than the third, thus resembling aldrichi, hirsuteron or cacothius. 
From the first two it differs in the larva, that of hirsuteron 
while having spicular skin, has a much larger comb, and the 
air-lube is shorter and without detached teeth of the pecten. 
Aldrkhi is even more dissimilar, and has a different habit, fre- 
quenting large flood-pools. In com])arison with cacothius, it is 
somewhat larger, while the mesonotal markings do not corre- 
spond, being the usual double brown band on a yellowish gray 
ground, whereas cacothius has a dark grizzled appearance with 
the lines narrow and illy contrasted. Specimens were also 
taken, wing-veins all dark, as follows : 

Cou>RAD(): Granby, June 1923 (H. G. Dyar). 

Fraser Rivci, June 20, 1923 ( H. G. Dyar). 

Aedes communis DeGeer. 

The commonest sjx^cies alx)ut Grand Lake out of doors. The 
first adult was taken flying June 3. The larvae were abundant 
in low-lying grassy pools about the lake and in the edges of 
small ix)nds. Also in great numbers in a single pool near the 
river* (North Fork of the Colorado) below Camp Wheeler. The 
bred adults are almost uniformly of the normal Uisarensis 

Aedes pionips Dyar. 

The larvae were found in a succession of small ponds for 
five miles up the valley of the East Inlet of Grand Lake. 
Communis bred out earlier in the edges of these ponds and 
after they were gone the large pionips larvae could be found 
scattered in the deep water. They were accompanied by num- 



bers of the larvae of Corethra which, however, did not seem 
to molest the fully grown larvae. Adults of pionips began to 
emerge after the middle of June. 

Aedes cataphylla Dyar. 

The earliest species on the wing at Grand Lake, the adults 
in May. The larvae occurred in most of the pools, but especially 
the open ones in grassy meadows filled by snow-water. A pupa 
was taken from a pool at Fraser, Colorado, the adult appearing 
May 31, 1923. 

Aedes impiger Walker. 

With cataphylla at Grand Lake in larger proportion and a 
little later in emergence on the average. Larvae in late pools 
were mostly impiger, the usual proportion between these species 
being reversed. Adults of impiger, last of May and first 
of June. 

Aedes dorsalis M eigen. 

Recorded by Cockerell from lower altitudes (as curriei). 
Absent at Grand Lake (8,000 feet). 

Aedes pullatus Coquillett. 

Occurring at various places about Grand Lake mixed with 
other species in lesser proportion, at the highest altitudes oc- 
curring alone (except for a form of punctor referred to under 
that heading).

conspicuous by being the only mosquito to enter the houses. 



Dates of emergence at Grand Lake, May 31 to June 6 ; adults

Aedes cinereus Meigen. 

Occurring at Grand Lake in most of the pools after the 
other moscjuitoes had nearly all emerged. The first adults were 
obtained on July 3, 1!)23. 

Culiseta incidens Thomson. 

Only one record is known to me, viz: 

CoLORAix) : Plateau Canyon below Mesa, 30 miles cast of Grand 
Junction (7,000 feet), August 23, lOOO (E. P. 

Culiseta inomatus Williston. 

Recorded by Cockerell up to 10,000 feet, but not met with 
by me at Grand Lake. I have the following records:

(Dtptera, Culkidac) 

Culex (Choeroporpa) dornarum, new species. 

A small black Culex, the male palpi exceeding the proboscis 
by the length of the last joint; wing-scales on the forks of 
the second vein ovate, but not very broadly so; flat scales on 
the occiput, black, mixed with whitish; no light markings 
visible on body or legs, the coloration in general similar to 
other species of the subgenus. 

Male hypopygium. Side-piece curved, conically tapered out- 
wardly; clasper swollen on outer third, with snout-shaped 
termination ; spine appendiculate ; dorsal declivity very min- 
utely pilose. Inner division of lobe of side-piece furcate, with 
two long distorted filaments, the inner one arising basad of 
the outer from a shorter arm. Outer division with four fila- 
ments on outer aspect, a blade-shaped one at the base of the 
short inner arm, which bears a long hooked filament and a 
short one. First mesosomal plate short, with furcate tip, the 
arms both long, slender and pointed; second plates exceeding 



them, with spatulate lip; tenth sternites rather short, with 
comb-shaped tip of about 12 teeth; ninth tergites small, fan- 
shaped, setose. 

Type, male. Sweet Water Reservoir, Fort Sherman, Canal 
Zone, Panama, September 5, 1923 (R. C. Shannon) ; paratype, 
male, Fort Sherman, Canal Zone, December 15, 1920 (J. B. 
Shropshire, through C. S. Ludlow). 

Near elevator 1). & K., hut the mesosomal plate with sharp 
pointed arms instead of rounded plate-like ones. 

Named for Mrs. Adam Dorn and Miss Annie Dorn, whose 
kind hospitality at Gatun the writers well remember. 

Culex (Choeroporpa) conspirator Dyar & Knab. 

This species was described from Mexico and Salvador, but 
though most of the Panama records given in the monograph 
are incorrect, the species does occur in Panama as shown by 
the senior author (Ins. Ins. Mens., xi, 09, 1923). To the 
synonymy dysmathes D, & L. — pasadaemon Dyar, we must 
now add mcrodaemov Dyar, as the senior author has con- 
vinced himself that the structures described under this name 
are not in reality different, but simply in a different position. 

The junior author made collections in the Cardenas River 
at Fort Clayton, Canal Zone, at the end of the dry season, 
April, 1923, The river at this point runs over stones, is well 
shaded, and at the time visited was low. Little bays or pools 
along the edge, full of leaves, driftwood and algae furnished 
the collections. Several species of Anopheles were present and 
several species of Choeroporpa, among them conspirator. We 
have the species from both the Pacific and Atlantic sides. 
Culex (Choeroporpa) fatuator, new species. 

This form has been confused with conspirator and occurred 
with it in the Cardenas River mentioned above. The adults 
are essentially similar to conspirator, but in the male hypo- 
pygium the points of the mesosomal plate are sharp, and project 
laterally parallel to each other. Type, male, Cardenas River, 
Canal Zone, Panama, April, 1923 (R. C. Shannon). 

One of the “t 3 T)es’^ of dysmathes D. & L. (the original 
specimen on which the determination as “new*' was made by 



Doctor Dyar) is this species, but it is not a specimen from 
which the description was drawn up, not agreeing therewith, 
and therefore the name cannot be used for this form. A series 
before us, Chagres River, June 7, 1907 (A. Busck) belongs 
to fatuator, 

Culex (Choeroporpa) cuclyx, new species. 

Palpi exceeding the proboscis by the length of the last 
joint, both black scaled. Head with flat scales reaching well 
up the sides, replaced by narrow ones at the vertex, white, or 
with a strong white reflection, mixed with black ones; forked 
black scales on the nape. Mesonotum with rather coarse bronzy 
brown scales. Abdomen black scaled with white basal seg* 
mental bands above, not reaching the sides; venter blackish. 
Wing scales rather broadly elliptical, more narrowly so on 
the bases of the fork of the second vein. Tarsi unhanded. 

Male hypopygium. Outer division of the lobe with a thick, 
inner arm, bearing a long filament with hooked tip and a 
shorter one; four flattened filaments arising in a group from 
a rounded projection at base of stem, without leaf, the .structure 
much as in epanastasis Dyar (Ins. Ins. Mens., x, PI. V, fig. 5, 
19)31^), except that the outer arm is rudimentary. Inner 
division short, of two fused cones, the inner one shorter, each 
bearing a long filament with flattened pointed tip; the two 
arms are not really apart, yet the structure so nearly approaches 
normal that it will be preferable to list the species under the 
heading ‘‘inner division of the lobe of side-piece with the arms 
apart.'' Tenth sternites long, with flattened comb-shaped tips. 
Mesosomal plate with a third point, subapical, the upper limb 
short and pointed, the lower long, parallel-sided with rounded 
tip, directed laterally, the third point sharp and parallel to it. 
Ninth tergites large, elliptical, broad, approximate at base and 
diverging, setose. 

Type, male, Cardenas River, Fort Qayton, Canal Zone, 
Panama, April, 19*^3 (R. C. Shannon).

{Dipt era) 


The new species of Diptera described in this paper were 
included in material sent to me by my friends, Prof. Teiso 
Esaki and Dr. Tokuichi Shiraki. With the exception of the 
Formosan Ptychoptera, the flies were taken in the mountainous 
sections of central Honshiu by Professor Esaki. The two 
genera, Bittacomorphella and Diomonus, are of especial interest 
in that all of the species known hitherto are Nearctic. The 
types are preserved in the writer’s collection through the kind- 
ness of the collectors. 


Ptychoptera formosensis, new species 

Male — Length 8.4 mm. ; wing 8.6 mm. 

Frontal prolongation of head and the palpi pale brownish 
yellow, the distal segments of the latter a little darker. 
Antennae with the scape and base of the first flagellar segment 
yellow, the remainder of the flagellum brownish black. Vertex 
and occiput broad, shiny blue-black. 

Mesonotum deep black, the praescutum with deep, longi- 
tudinal impressions ; scutellum reddish yellow ; postnotum blue- 
black. Pleura and pleurotergites of postnotum light yellow. 
Halteres brown. Legs with the coxae light yellow ; trochanters 
light yellow: femora obscure yellow, the tips narrowly dark- 
ened ; tibiae pale brown, the tips narrowly darker ; tarsi brown. 




Wings with a faint grayish tinge, the costal and subcostal cells 
more yellowish; two very narrow cross-bands, one along the 
cord extending from R to midlength of CWgj the second band 
more oblique, slightly interrupted, extending from the stigma 
at the tip of /?i to the fork of M. Wing-surface with the 
macrotrichiae extensive, in the basal cells extending almost to 
the base. Venation: Rs shorter than r-w, the latter subequal 
to m-cu and in alignment ; abortive anal vein conspicuous and 
with macrotrichiae. 

Abdomen orange-yellow ; tergites two to six with the caudal 
margins broadly black; segments seven and eight black; 
hypopygium orange; sternites uniformly dull orange. Male 
hypopygium large, the ninth tergite profoundly incised, the 
lateral lobes being very long, digitiform, their tips directed 
ventrad across the genital chamber. 

Habitat . — Japan (Taiwan ) . 

Holotype, cJ', Funkiko, April 25, 1917 (T. Shiraki). 

The present species is most closely related to P. annandalei 
Brunetti (India). I am indebted to Dr. Annandale for the 
privilege of .studying one of the type males of the latter species. 
The following supplementary notes on P. annandalei may be 
supplied : 

The coloration of the mesonotal praescutum is brilliant 
metallic blue with decided opalescent reflections; the anterior 
part of the postnotum with a large circular light yellow area 
with opalescent reflections. Venation with the deflection of 
short to subobsolete, r-m being correspondingly length- 
ened; cell 7?4 much shorter in proportion to the length of its 
petiole {/? 4+0 than in formosensis. 

The ninth tergite is very short at its base, the lateral lobes 
being greatly prolonged into slender, digitiform pale lobes that 
are slightly enlarged at their distal ends and here provided with 
black setae. Dististyle complex, consisting of a flattened blade 
whose dorsal inner edge is provided with a broad margin of 
short, blackened teeth, the ventral distal angle produced laterad 
and caudad into a pale, fleshy clavate lobe that is provided with 
several coarse, erect bristles; mesal face of this blade, near 



the base, produced mesad into a subconical lobe that is pro- 
vided with short setae, especially on the cephalic face and near 
the apex. Ninth sternite appearing as two stout reddish brown 
lateral lobes, the truncate apex of each densely provided with 
light yellow appressed silken setae, the caudal face with a 
dense pencil or fascicle of black setae directed mesad and 
caudad, not quite contiguous across the mid-line; notch be- 
tween the lobes U-shaped ; back of this notch a median lobe 
that is slightly widened distally, the apex truncate. Aedeagus 
conspicuous, subtended on either side by a small chitinized 
apophyse, which terminates in a small point directed ventrad 
and laterad. 

In P, formosensis, the tergite is generally similar but the 
dististyle and ninth sternite are entirely different in structure, 
the chitinized lobes being replaced by silken yellow setae. 

Bittacomorphella nipponensis, new species. 

Female , — Length 10-11 mm.; wing 7.6-9.4 mm. 

Rostrum silvery; palpi pale yellow. Antennae setaceous, 
black throughout. Head black, the front, anterior part of 
vertex and the orbits silvery white. 

Mesonotal praescutum and scutum black, the lateral margins 
broadly silvery: scutellum brown; postnotum pale brownish 
silvery. Pleura blackish, heavily silvery pruinose. Halteres long, 
pale, the knobs infuscated. Legs with the fore coxae blackened, 
the remaining coxae and the trochanters reddish yellow ; femora 
pale basally, passing into brownish black at the tips, the fore 
and middle femora only narrowly pale basally, the posterior 
femora with only the tips darkened: tibiae black, hairy; basi- 
tarsi black, the apical two-fifths (fore leg), one-third (middle 
leg) or one-fifth (posterior leg) snowy-white; tarsal segments 
two and three snowy-white; terminal two segments abruptly" 
narrowed, brownish black. Wings gray, the small stigma pale 
brown; extreme base of wing faintly yellowish; veins black.

of cells 5*fi, /?;, and Venation about as in B, sackeni. 

Abdomen dark brown, the caudal margins of the segments 


INSECUTOR insciti;e menstruus 

narrowly paler; terminal abdominal segments with appressed 
silvery pubescence.

Paratype, $, Ozenuma, on boundary between Iwashiro-no- 
kuni and Kotsuke-no-kuni, altitude 6,645 feet, July 26, 1923 
(T. Esaki). 

Biitacomorphella nipponensis is most closely related to B. 
sackcni (Roder) of western North America, from which it 
diflFers notably in the great reduction in number of macrotrichiae 
in the cells of the wing. In sackeni these include the entire 
distal sixth of the wing. 

Blepharocera esakii, new species.

brown stripes, the median stripe broad and indistinctly bisected 
by a capillary pale line; an incomplete transverse suture, ex- 
tending mesad to the mesal edge of the lateral praescutal stripes ; 
scutal lobes dark brown, the median area light gray pruinose; 
scutellum light gray, the caudal margin broadly black; post- 
notum very short, gray pruinose. Pleura light gray pruinose. 
Halteres obscure orange-yellow throughout. Legs with the 
outer faces of the coxae more or less darkened, the inner 
faces of the mid-coxae and trochanters with dense black setae ; 
femora and tibiae obscure yellow, the tips broadly dark brown ; 
tarsi dark brown. Wings subhyaline, the extreme base con- 
spicuously light yellow; costal margin narrowly tinged with 
pale brown; veins black; Cu and its branches paler on basal 
.half. Venation: Rs long, fully five to six times the basal 
deflection of R^^.. 



Abdominal segments grayish brown, the basal tergite clearer 
gray, the extreme caudal margins of the segments pale. 

Habitat. — Japan (Honshiu). 

Holotype, Mt. Takao, Musashi-no-kuni, altitude about 
500 feet, May 7, 1922 (T. Esaki) ; beside a stream in dense 

This interesting Blepharocera is named in honor of the 
collector, my friend, Prof. Teiso Esaki. B. shirakii Alexander 
is readily told from the present species by its general black 
coloration and smaller size. 

Macrocera ephemeraeformis, new species. 

Male . — Length about 9.5 mm. ; wing 8.4 mm. ; antenna 27 mm. 

Front and palpi brownish black. Antennae very long, as 
shown by the measurements ; basal segment of scape glabrous, 
obscure yellow basally, the apex blackened; second segment 
very short; basal segment of flagellum brown on basal third, 
the apex yellowish white; succeeding flagellar segments with 
the basal third black, the apex yellowish, the amount of black 
becoming further reduced on the intermediate and terminal 
segments. Head black. 

Mesonotum light brown, sparsely yellowish pollinose, with 
three conspicuous shiny black stripes ; scutellum and postnotum 
chiefly dark brown. Pleura black, the region surrounding the 
wing-root light brown, Halteres testaceous, the knobs yellow. 
Legs with the fore and middle coxae obscure yellow, the an- 
terior face more infuscated; posterior coxae largely brown; 
trochanters brownish yellow; fore femora brown, near the 
apex with a conspicuous subterminal spine; posterior femora 
yellow; remainder of legs passing into brown. Wings grayish 
subhyaline, the costal region variegated with bright yellow and 
brown, the markings alternately arranged; the brown marks 
include conspicuous seams at h; tip of ; tip of ; arculus; 
origin of Rs; a large blotch at fusion of R and M, continued 
caudad as a paler cloud along vein Cu^ almost to the wing- 
margin; a spot on opposite to and nearly confluent with 



the area at ; on and a conspicuous apical cloud continued 
back along vein ; veins yellow, brown in the infuscated 
areas; a very small paler brown cloud at tip of vein Cu^ but 
none at tips of the medial veins. Anal angle of wing square^ 
more so than in any described species of the genus. Venation:

relatively extensive, about two-thirds the section of M beyond it. 

Abdomen with the basal five segments obscure yellow, the 
caudal margins of the segments conspicuously blackened; ter- 
minal segments and hypopygium uniformly blackened. 

Habitat . — Japan (Honshiu). 

Holotypc, c?, Mountains near Kawamata, Shimotsuke-no- 
kuni, July 24, 1923 (T. Esaki). 

This remarkable fungus-gnat is the largest species of the 
genus known to the writer. In its general appearance it differs 
so strikingly from the Nearctic species of Macrocera that it 
might appear that a new genus is necessary for its reception. 
The Oriental Af. altermta Brunetti, however, appears to form 
a connecting link between the groups. The anal angle of the 
present species is practically rectangular. The specific name 
was suggested by Professor Esaki, the fly presenting a curious 
resemblance to certain may-flies, as Heptagenia and Ephemera. 

Diomonus esakii, new species. 

Male . — Length 11.5 mm.; wing 11.4 mm. 

Female . — Length 11 mm.; wing 10.2 mm. 

Rostrum and palpi black. Antennae black, the terminal six 
segments abruptly yellowish white. Head shiny black, the 
yellowish ocelli placed in almost a transverse line, the median 
one a little smaller than the laterals. 

Thorax entirely coal-black, with short, delicate black pile. 
Halteres black, the extreme base of the stem a little brighter. 
Legs with the coxae black, very slightly pruinose; trochanters 
and extreme bases of femora yellow; remainder of l^s black, 
the terminal tarsal segment a little paler; no spine on mid- 
femur. Wings subhyaline, the costal margin more yellowish; 
apical fourth of wing uniformly infuscated; an irregularly 



circular brown cloud in the bases of cells and and a 
conspicuous wash at the end of vein Cu ^ ; veins brown, darker 
in the clouded areas. Venation: Sc^ ending some distance 
beyond the origin of Rs, Scn immediately before this origin 
in the female, far before in the male; cell i ?2 very tiny, sub- 
quadrate in the female, completely obliterated in the male; tip 
of anal vein atrophied. 

Abdomen black. 

In the female, the basal tarsal segments are paler than in 
the male and the abdomen shows faint bluish reflections. 

Habitat , — ^Japan (Honshiu). 

Holotype, Yumoto, Shimotsuke-no-kuni, altitude 5,820 
feet, July 23, 1923 (T. Esaki). 


This beautiful and striking fungus-gnat is named in honor 
of the collector, Professor Esaki. The previously described 
species of Diomonus are all Nearctic. The obliteration of 
cell 7?2 in the type male is presumably an abnormality of the 
specimen. Such individuals would run to the subfamily 
Mycetophilinae. The nearest ally of D, esakii is the genotype, 
D. nebulosus Walker.

Of the recent catalogues of Indian insects being issued by 
the Government of India, Part 2 covers the Culicidae, by 
Ronald Senior-White. Without attempting any criticism of 
the main oj^ject of the work, some incidental references to 
American mosquitoes require notice. 

Aedeom3da squamipennis Lynch Arrihalzaga. 

This is recorded as an Indian species (page 48), but erro- 
neously. Cafasticta Knab is the only Oriental member of the 
genus, the references to squamipennis as Oriental being based 
on misidentifications. 

Heteronycha I-ynch Arrihalzaga. 

This is given as a synonym of Aedes Meigen (sensu strict.), 
and the type is stated to be Culex acstuans Wied. (as dolosa 
Arrib.) (page 62). As Mr. White gives the subgenera of 
Aedes (sensu lat.) full generic rank, this is a misplacement. 
He should have given Heteronycha under Ochlerotatus, as to 
which it has priority. That is assuming that the reference by 
Howard, Dyar and Knab of Heteronycha to Aedes is correct. 
This seems the only interpretation possible from the descrip- 
tion ; but Doctors Barbara and Petrocchi of Buenos Aires have 
contended to me that they feel sure that Lynch described as 
Heteronycha dolosa a common Culex of the region, Culex 
bonariensis Brethes, and that his description of the claws of 
the female as toothed was the result of an error. They think 
he confused his slides. I accepted this determination on other 



grounds (Ins. Ins. Mens., ix, 160, 1921). Later, in the Mos- 
quitoes of the United' States, I reverted to the position taken 
in the monograph, and published some additional remarks on 
the subject (Proc. U. S. Nat. Mus., xlii, 3, 1922), which is 
still far from clear. In any event the placing of Heteranycha 
under A'edcs Meig. (sensu strict.) is incorrect, and the type is 
dolosa Arrib., but not aestuans Wied. (:=^uinquefasciatus Say). 

Aedes (Stegomyia) aeg 3 rpti Linnaeus. 

Mr. White lists this as ''Stegomyia fasciata Fab.*' (page 68), 
although he realizes by the s)mon 3 rmy that the name fasciata 
was preoccupied when proposed. This is presumably justified 
on the transference of Fabricius’ name to Stegomyia; but this 
proceeding is not justified by the rules. He does not use the 
name aegypti Linn, because it appears to him that that name 
might equally well refer to Aides dorsalis Meigen. Now, even 
if so, as a positive reference of the name has been made by 
me, this should hold ; but it is evident from the description that 
aegypti cannot refer to dorsalis, Linnaeus mentions a shining 
transverse line behind the thorax and before the abdomen. 
Nothing on dorsalis represents this, but the silvery scales on 
the scutellum of the ‘‘yellow fever mosquito’’ correspond ex- 
actly, as when seen under a low power they present the ap- 
pearance of a shining silvery transverse line. There does not 
appear to me to be the slightest doubt of the identification of 

Cacomyia Coquillett. 

Given (page 73) as a doubtful synonym of Ochlerotatus. 
The name is a synonym of Haemagogiis (See Ins. Ins. Mens., 
ix, 101, 1921). 

Stegoconops Lutz. 

Given (page 76) also as a doubtful synonjrm of Ochlerotatus. 
This is again Haemagogus, and it may be that Mr. White con- 
siders Hacfitagogus as doubtfully synonymous Mrith OcMero* 
tatus. However, he does not give Haemagogus itself in the 
synonymy, which he should logically do if thi.s supposition 
were correct. 



Aedes alpinus Linnaeus. 

This is given (page 79) as nigripes 2ett., the references to 
Linnaeus’ earlier name having been overlooked (See Ins. Ins. 
Mens., viii, 53, 1920, and x, 73, 1922). Walker’s names 
impiger and implacabilis are given as doubtful synonyms, but 
they represent two valid American species (See as to impiger 
Ins. Ins. Mens., viii, 8, 1920, and as to implacabilis, Ins. Ins. 
Mens., xii, 26, 1924). 

Theobaldia Neveu-Lemaire (Culiseta Felt). 

The subgeneric name Allothcobaldia Brolemann has been 
omitted (page 84). CuHcclla Felt, another subgenus, appears 
wrongly in the synonymy of Culex (page 97). The name 
Culiseta is misspelled CuHcefa 

Pneumaculfx Dyar. 

This is given in the synonymy of Culex (page 99), and is 
credited to Theobald. It is in reality a synonym of Ortho- 
podomyia, and is correctly entered in the monogragh (Howard, 
Dyar & Knab, Mosq. No. & Cent. Am & W. I., iv, 877, 1917). 

Thomasina Newstead & Carter. 

Also erroneously given in the synonymy of Culex (page 99) 
and misspelled Thomascina. This genus is also a synonym of 

Runchomyia Theobald, Binotia Blanchard. 

These names are given as synonyms of Rachionofomyia (page 
113), although they antedate that name. In fact they have 
nothing to do with it, being synonyms of Gocldia, an American 
genus of predaceous Sabethids. Rachionotomyia does not occur 
in America, nor Goeldia in the Orient. 

Wycomyia, Dcndromyia and Phoniomyia Theobald. 

It is doubtful if any of the Oriental species actually belong 
to IVyeomyia or its subdivisions, except perhaps nepenthicola 
Banks of the Philippines. The species in the Indian catalogue 
are referable to Heinzmannia Ludlow (See Edwards, Ind. 
Journ. Trop. Med., x, 445, 1922). 



The correct uses of American names, under the conceptions 
adopted in the catalogue, are not referred to in the preceding. 
Several of the synonyms of Aides (as Ochlerotatus) and Ctdex 
are correctly given, though by no means all of the names that 
could have been quoted are given. 


{Dipt era) 


In working up the fungus gnats of British Columbia I am 
particularly indebted to Mr. R. S. Sherman, who has spent 
much time on this family in the Coast Division from where he 
has described 20 or more new, and has sent me many species 
to work over, several of which I believe to be new. I am also 
greatly indebted to Col. C. H. Pollen, who has for many years 
done so much to help my studies in every way. 

In the difficult genera Bcletim and Mycomya it seems quite 
useless to describe one wing, owing to the variation shown in 
the series; but an average one is selected. The females seem 
hopeless at least as far as characters to connect them to their 
truthful mate. This has largely to be done by date and locality. 
Before me are several apparently not described, but except in 
a single case, I have refrained from describing, as I do not 
think the male may ever be properly connected with them. 

The males have been studied chiefly by the hypopygiiim, and 
slides of nearly all species described are on hand. Most females 
have been considered as paratypes, and paratype males without 
the hypopygium mounted have been numbered. 

Paratypes of some species will be found in the Canadian 
National Collection, the U. S. National Collection, and in that 
of R. S. Sherman. The remainder are in the author’s collection. 

Mycomya terminata, new species. 

Head grey-black; mouth parts and palpi yellow; antennae 
‘Scape and base of flagellum I, yellow, the remainder black* 
brown; all segments twice as long as wide. Thorax, dorsum 



grey-black ; no vittae, but they are indicated by reflection, being 
slightly polished. Extreme humeral edge showing a brown 
shade. Bristles and hair dorsally black, laterally brown, with 
some black. Scutellum dark with two pairs of bristles. Pro- 
pleura yellow brown, all others blackish, the pteropleura paler. 
Abdomen dark brown, with brown pilosity. Coxae yellow, the 
two hind darker, mid-coxal spurs weak, long and rather straight 
with the tip bent. Wing; C reaches the apex of the wing. 
Sc enters C proximad but nearly over mid cell R ; Sc2 is 
proximad of the latter. Petiole of M shorter than M2; CU 
forks below cell R which is long trapezoidal, being over twice 
as long as deep. Hypopygium dark, some of the minor parts 
brown ; tergite ; from near the center issue a pair of chiti- 
nized points (in cranhrooki and caulficldi called A) ; from near 
the lateral corner rises a large, fleshy, elongate oblong lobe, the 
inner tip of which has a rounded chitinized point directed 
inward (called B) ; from below this and near the middle of 
the lobe there is a chitinized point with a very long terminal 
bristle which sometimes branches near its middle. The sternite 
half near its center has a pair of triangular pyramids on the 
apex of which is a hinge, working a long chitinized projection, 
with an angle near its tip and two points at its apex (called C). 
(In pinned specimens C is usually completely folded in and 
not seen.) Between these and near the middle are a pair of 
thread-like chitinized prongs (called D). There are other 
lesser spikes from within the center. 

Described from 8 males from \"ancouver and Savary Island, 
B. C., in March and April. It is hard to limit the number of 
females by the variation ; probably 5. The are as the but 
seem browner on the thorax. All specimens taken by R. S. 

Mycomya cranbrooki, new species. 

Male; similar to termimta, differing as follows: Palpi dark; 
all hairs and bristles of the dorsum brown; propleura black. 
The wing is between terminata and caufieldi in Scl, Sc2; 
petiole of M about equal to M2; CU forks slightly proximad

of mid cell R. Hypopygium A is smaller. B is not distinctly 
chitinized and of slightly different shape, with the long ter- 
minal bristle shorter. C is parallel sided, its two apical points 
very small and short. D is differently shaped. 

Holotype, Cranbrook, B. C., May 27 (C. B. Garrett). 

Mycomya canlHeldi, new species. 

Similar to terminal a. with the hypopygium different. The 
tergite half runs to a short central point, thus A is absent. 
The lateral flaps B are broad, not elongate. C is of different 
shape and ends in a single triangular point.

the remainder dark brown, each segment about twice as long 
as wide. Thorax, dorsum obscure brown, primrose grey or 
all grey-black, no distinct vitta, but with a light brown patch 
behind the humeri. Proplcura yellow, the remainder dark, 
brown -black. Abdomen, tergites dark brown with posterior 
margins yellowish. Venter sometimes pale. Coxae yellow, the 
hind one darker or infuscate, the spurs of the mid coxae are 
moderately long, and curved. Wing; C ends slightly beyond 
the apex of the wing ; Sc enters C about over mid cell R ; Sc2 
is proximad of the middle of cell R which is trapezoidal, the 
shorter side being not much longer than the ends. Petiole of 
M slightly longer than M2. Cu forks below or more than the 
length of the RM cross vein proximad of it. Hypopygium 
yellowish, all pieces seem chitinized except the lateral flaps 
which may also be. Tergite half, dorsally in the center runs 
out into a long projection having a thin apex but a very broad 
base. The lower lateral corners run out into a long narrow 
oval flap pilose on the outer side. Sternite half with two 
cerci looking projections in the center which reach the arc 
made by the lateral flaps ; to the side of these, but from within 



a pair of sharp long spikes rise which also nearly reach the arc. 
There seem two other pairs of short spikes in the middle.

Mycomya vulgaris, new species. 

Male head grey black, mouth parts and palpi yellow. An- 
tennal scape and base of first flagellar segment yellow, the 
remainder black except the first ; each segment is hardly twice 
as long as wide. Thorax; dorsum grey black, opaque, the 
usual three vittae hardly visible, being a browner shade only.

Wing; C not produced past Rl, 5; Sc ends in C slightly distad 
of mid cell R; Sc2 over the mid cell, which is trapezoidal, its 
short side about twice as long as the ends. Cross vein RM 
about equal to the basal sections of RS. The tip of R4, 5 
drops almost to the level of fork of M. Petiole of M shorter 
than M2, M forks over the tip of CU2; CU forks below or 
proximad of the RM cross vein. Hypopygium dark. Tergite 
half all chitinized large and appears like the top half of a 
sparrow s beak. This is composed of an inner and outer part. 
At the lower side of the tergite is a rather short cylindrical 
projection (about one-third the length of the beak) which 
terminates in three hairs. Sternite half in the middle has three 
pairs of triangular points from the center of the inside a soft 
bi-lobed pad rises yellowish and with pale pilosity. 



The female is similar. The scape is not so yellow, it is 
darker. The flagellar segments are not twice as long as broad ; 
the abdomen sometimes shows shadings of pale posterior edges 
brown yellow. The fore coxae has no inner bristle and mid 
coxae no spurs. 

Described from 131 males and 55 females all from Femic, 
B. C., July 21-29 (C. B. Garrett). 

Mycomya magna, new species. 

Male. The entire description of vulgaris applies to this 
species, except flagellum segments twice as long as broad. Both 
pairs of scutellum bristles are about equal in length. Abdom- 
inal ventrites 2 to 4 always brown yellow. Fore coxae with 
no inner lateral bristle, but a row of long hairs up that edge. 
Wing cell M often not twice as long as deep, leaving the tip 
of C over the distad end and Sc2 in the middle. CU forks 
more proximad. The hypopygium is somewhat similar to 
vulgaris but the beak has no inner piece, it being small, the 
cylindrical lateral projection is swollen oval club shaped and 
the entire apical half is set with fine pilosity. The points of 
the sternite half are slightly different, the whole together ap- 
pearing quite different. It is larger than vulgaris. Female as 
the male, but the tergite often has a posterior yellow margin. 

Described from 11 males, 13 females. Fernie, B. C., July 

Mycomya ampla, new species. 

Male. The description of vulgaris applies to this except 
the scape of the antennae is dark brown. The scutellum has 
one pair of bristles. The propleura is yellow. The tergites 
have a posterior yellow margin ; all the abdominal hairs brown 
yellow. The fore coxae have no mid bristle. The mid coxal 
spurs are short, reaching only to three-quarters of its own coxae 
and they are almost straight. Hypopygium ; tergite half along 
the middle edge with two pairs of thin flat oblong round tipped 
appendages. The lower lateral edge runs out into a long thin 
pale yellow fleshy lobe pilose on the outer side. The sternite 
half is cup shape, the top lateral edge running out and touching 


at their tips, the bottom between being transparent skin. There 
are other minor spines within. 

Female is as vulgaris but the scape more yellow. The abdo- 
men with posterior yellow margins. The fore coxae more 
thickly pilose. Sciitellum with one pair of bristles ; and SC in 
one wing does not reach C.

base brown, next joint black, base of flagellar one for one 
quarter yellow, all the remainder black brown. Except flagellar 
one, the segments are just over twice as long as wide. Scu- 
tellum brownish, two pairs of bristles. Abdomen tergite with 
posterior yellow margins, hairs black. Coxae yellow, their 
bases all muddy yellow, fore coxae sparingly haired with rela- 
tively longish hair. Mid coxal spurs about three quarters as 
long as their coxae. Wing C ends beyond the apex of the 
wing. Sc enters C over mid cell. R, Sc2 proximad of mid 
cell R which is twice as long as deep. Petiole of M equal or 
slightly longer than M2 ; CU forks proximad of the RM cross 
vein. Hypopygium, tergite half dorsally in the middle branches 
into two short points curved outward and their apex pilose. 
From near the lateral corners rise two oval or pear shaped 
flaps pilose on the outside. The sternite half, from the tip of 
the lateral corner makes a V hollow from the apex of the V 
(opposite the lateral corner) to the center of the sternite is a 
smaller V about half the length of the first (the whole appears 
like an M with an extra up line on each side). From within 
the usual mid pair of blades show between the central V and 
each side of the mid blades rise a pair of chitinized points 
with a common base. Centrally there is a soft fleshy pad. The 
female is similar but the flagellar segments are hardly twice 
as long as wide. 

Described from 6 males and 1 female, Cranbrook, B. C., 
April and May (C. Garrett), 

Mycomya shcrmani, new species.

other Sc ends at Sc2 which angles forward and joins cell R 


about its middle. The latter is not twice as long as deep, the 
end RS is almost equal to its next section. Petiole of M nearly 
equal to M2; CU forks below the proximad end of the RM 
cross vein. Fore coxae on the inner half in front sparingly 
haired with long fine hairs. Mid coxal spurs fragile, long and

(Dipt era) 


In the following treatment of the North American Luciliini, 
it is assumed that the three species determined by Hough and 
recognized subsequently as identical with the European species, 
Lucilia caesar Linne, L. syharum Meigen and L. sericata 
Meigen, are conspecific with the forms originally included under 
those names. The North American species herein recognized, 
L. pilatei Hough, L. australis Townsend, L. unicolor Townsend, 
L. occidentalis n. sp., L. pallescens n. sp, and Francilia alas- 
kcnsis n. gen. and sp., are assumed to be distinct from pre- 
viously described species. 

This is done for the following reasons: (1) The collection 
at hand of Old World species, authentically determined, is 
insufficient to make correct identification by means of com- 
parison; (2) the Old World species have not been sufficiently 
defined in many cases and this prevents accuracy of determina-

tion from literature; (3) in a number of cases, the type speci- 
mens are no longer in existence. Under these conditions any 
attempt to make final decisions upon the status of our species 
would prove unsatisfactory. It is proposed instead to describe 
our species as definitely as possible, which may enable other 
workers, better situated, to check our species with those of the 
Old World ; it is quite probable that others of our species will 
prove to be the same as those found in Europe besides the ones 
mentioned above, but meanwhile the names here used will be 
available for the North American forms. 

In the table of genera of Calliphoridae ^ it is stated that the 
subcostal sclerite in the Luciliini and Calliphorini is without 
small black bristles. In the following study it was found that 
the subcostal sclerite has small black setae in LucUia caesar, 
and this is apparently an infallible characteristic of this species. 

L. caesar appears to be the only species in North America 
with the subcostal sclerite setose, but the following Old World 
species, as they stand determined in the National Collection, 
also possess this characteristic: L. fasinanensis Macq. (Aus- 
tralia) ; L. ruficeps Mg. (Europe) ; L. nobilis Mg. (Europe) : 
L. simulatrix Pand. (Europe) ; L. inducta Wlk. (Asia) ; 
L, fortunata Wlk. (Philippines); L. {Hemipyrellia Tns. is 
synonym of Lucilia) curriei Tns. (Africa). Just how the 
application of this character would affect the status of these 
species, in regard to L. caesar, is a matter for the future. 

Malloch has called attention ® to the fact that Cryptolucilia 
{OrthcUia Pseudopyrellia), is closely related to Lucilia, the 
two genera possessing in common a peailiar character, namely, 
a tuft of hairs on a chitinized area (tympanic ridge, Lowne, 
Awati) which borders onto the attachment of the lower squama 
to the thorax. This tuft is here called the para-squamal tuft 
(see below discussion on the thoracic alar cavities). Also 
Cryptolucilia (all species?) has the subcostal sclerite setose as 
in Lucilia. Pyrellia serena Mg. (N. A.), has the subcostal 
sclerite setose, but these setae are absent in Morellia micans

»Ann. Mag Nat. Hist., vol 12. 5(MS. 



Macq. (N. A.). In Cryptolucilia the hypopleural bristles are 
represented by a number of fine hairs which serve to distin- 
guish it from Lucilia, and on the basis of this character the 
two genera are placed in diflFerent families. This character, 
the presence or absence of hypopleurals, is not, as Malloch 
states,^ always a sharply defined one and does not definitely 
separate Muscoidea in two distinct series the way they are now 
considered, as transitory stages can he found in a number of 

It may be well to mention an easily apparent biological con- 
dition in the Muscoid flies which seems to be correlated with 
the presence or absence of hypopleural bristles. The forms 
without hypopleurals ( Scatophagidae, Anthomyidae and Mus- 
cidae) are in the larval stages, as a general rule, plant feeders 
or live in the excrement of herbivores ; while those with hypo- 
pleiirals (Calliphoridac,' Sarcophagidae, Dexiidae, Tachinidae) 
are carrion feeders, or parasites, or live in the excrement of 
carnivores. A large number of exceptions can be pointed out 
but it is significant that most of these exceptions occur in the 
groups showing tnansitory stages of the hypopleural bristles. 
Thus, the Muscoid series of flies present an unbroken series 
of larval food habits, ranging gradually from one food sub- 
stance to another probably in the following manner : beginning 
first with feeders in dead vegetable matter and leading, on the 
one hand, to feeders on living vegetable matter and, on the 
other hand, to (1) feeders on excrement of herbivores, (2) 
excrement of omnivores (e. g., man), (3) excrement of car- 
nivores, (4) carrion, (5) parasites of vertebrates, (6) parasites 
of invertebrates, insects, mollusks, worms, etc. The Calli- 
phoridae and Sarcophagidae in one species or another range 
through all of these habits except that (as far as known) of 
being feeders on living plant tissue. In a general way it can 
be stated that the forms without hypopleurals are plant feeders 
(living or dead plants) and those with hypopleurals are flesh 
feeders. In fact, it seems apparent that the presence or ab- 
sence of the hypopleurals marks the “parting of the ways” in 

*Aniif Majf Nat Hist , vol lli, WKi 



the Cyclorrhapha Myodaria, on the one hand leading toward 
the Acalypterae through the Muscidae, Anthomyidae and 
Scatophagidae, and on the other hand the “path’' is along the 
Calliphoridae and Sarcophagidae toward the highly specialized 
Dexiidae and Tachinidae. The transitional forms, indefinite as 
to presence or absence of hypopleurals and larval habits, would 
mark the point at which the separation took place. The aber- 
rant forms, in reference to larval habits, represent the 
“strayers” from their respective paths. One such “wayward" 
genus is Gastrophilus, a genus until recently placed in the 
Oestridae. It does not possess the hypopleural bristles and for 
this, and other reasons, the genus is now placed in the Antho- 
myidae. At first glance the parasitic (bot) habits of Gastro* 
philus appear to be a distinct exception to the plant (living 
and dead) habits of its congeners. However, as the species live 
in the alimentary tract of herbivores (Equidae) their parasitic 
habit may be an adaption readily obtained through a previous 
plant feeding habit. 

The following remarks appertain to certain structural features 
to be found in what are here termed the thoracic alar cavities^ 
particularly the posterior one. Both are rather shallow. The 
anterior one lies behind the prealar callus and immediately 
laterad and l)elow the supra-alar ridge (i. e., the mesonotal 
ridge whereon the supra-alar bristles are placed) and is bounded 
behind by a sharp ridge, the intra-alar ridge. This ridge ex- 
tends from the point where the anterior bristle of the post-alar 
callus is located clear to the wing base. The intra-alar ridge 
divides the anterior thoracic alar cavity from the posterior one. 
When the wings are folded the humeral part of the wing, the 
epaulet, basi-costa and the base of the first vein, i. e., stem 
vein, rest in the anterior cavity. The basal part of the stem 
vein rests immediately upon the intra-alar ridge. 

The posterior alar cavity is bounded above (dorsad-mesad) 
by the ridge formed by the combination of the intra-alar ridge 
with the post -alar ridge. Behind, the cavity is enclosed by the 
•vertical margin of the scutellum, while its lower margin is 
bounded by the anterior margin (i. e., the attachment) of the 



lower squama. In this cavity, when the wings are folded, the 
alula of the wing and the upper squama are nested. 

The posterior alar cavity itself is divided longitudinally into 
two more or less equal parts by a well defined suture. The 
upper vertical section is the post-alar declivity which is setose 
in the Calliphoridae and allies (Malloch). The lower section, 
or tympanic plate (Lowne,^ Awati^) is more of less flat and 
triangular in outline, and is made up of two apparently diflFerent 
parts. The anterior part, typmpanic membrane, immediately 
below the base of the wing, is hollowed out and within this 
pocket, tympanic pit, the species of Lucilia have a tuft of hairs. 
Within this pit, according to Lowne, is a “spiracle*' which 
may have the function of an auditory organ. In Francilia 
alaskensis (new genus and species) the upper anterior margin 
of the pit is broadened and on this the hairs are placed instead 
of being down in the pit. This tuft of hairs is absent in 
Cryptolucilia, The posterior part or tympanic ridge appears 
as a cord-like prolongation of the lower corner of the scutellum 
extending l)etween the squama and lower margin of the post- 
alar declivity. It has a more or less chitinized ova! area bearing 
a patch of hairs (Malloch). This is here termed, for con- 
venience, the para-sqmimal iiift. It was noted above that this 
tuft is present in Cryptolndlui. Awati has called attention to an 
analogous condition in certain Old World species of Musca, 

In the descriptions below the abdominal tergites are num- 
bered in the way they appear. The first tergite is almost en- 
tirely fused with the second so that the two appear as one, 
hence they are usually considered as the first tergite. Three 
other tergites are readily visible and are numbered 2, 3 and 4, 
respectively (morphologically they are the third, fourth and 
fifth). Where the shape of the head is given, e. g., “head 
broader than high," the view of the head is that of the frontal 

The basicosta is readily aoparent as a very distinct structure. 
It IS a smooth, thin, scale-like structure and its lack of bristles

make it readily distinguishable lying as it does between the 
bristly alar epaulet and the base of the costa which also bears 
strong bristles. 

The subcostal sclerite is a small elongate triangular piece on 
the lower side of the wing extending from the basi-costa to the 
first vein. 

The species of Luctiia in the Nearctic region have the fol- 
lowing distribution: caesar and sylvarum are typically more 
northern forms (transitional and upper austral zones) and 
sericata, australis and pallescens are t3rpically more southern 
(upper and lower austral zones); pilatei is neotropical and 
extends into the lower austraU while elongata and F. alaskensis 
are known only from Washington and Alaska respectively. 
L. sericata is also fairly abundant in the transitional zone. 

L. sericata and caesar are well known as sheep maggots 
wherever extensive sheep raising is practiced. They have also 
been known to cause myiasis in man and animals but are com- 
monly breeders in refuse and carrion. L, sylvarum is known 
to parasitize toads in Europe, Practically nothing is known of 
the immature stages of the other species.

Lucilia pallescens, new species. 

Small species characterized by a very perceptible silvery 
pollen on thorax and abdomen giving a somewhat grayish tinge 
to the green metallic ground color. 

Male . — Head broadly oval in outline, the face but little pro- 
truding downward; front and face black, but densely overlaid 
with silvery pollen, except on frontal vitta, giving a silvery 
aspect to head. Front rather broad, its narrowest width is 
nearly as broad as length of third antennal joint. Antennae 
rather small; arista slightly longer than antenna. Parafacial 
broader than frontal vitta. Facialia with only a few setae on 
lower portion. Wings slightly darkened ; basicosta light yellow ; 
squamae white. Hypopygium conspicuous (as in Sarcoph- 
agidae) ; lobes of fifth sternite long, ligulate, with dense long 
hairs. Outer forceps straight, pointed ; inner ones straight, 
slender and pointed. 

Female . — Head much broader than high; width of front 
nearly twice the length of third antennal joint; frontal vitta 
nearly twice width of parafrontal ; parafacial and parafrontal of 
nearly equal width.

Lucilia unicolor Townsend.^ 

Of the five specimens mentioned by Townsend when de- 
scribing Lucilia unicolor only one specimen can be found in 
the collection. This bears the type label, and is evidently the 
one recorded as the type since it bears the locality which 
Townsend gives for the type specimen, Mesilla, New Mexico. 

^Huscoid Flies, 119, 1908 



It is very similar to the specimens Townsend described as 
australis and oculata, but as it differs somewhat from australis 
it should, at least for the present, be considered as a separate 
form. If it subsequently proves to be the same species its 
name would have priority over australis as it appears first in 
the publication. It differs from australis mainly in having the 
head higher in proportion to its breadth; the front is broader 
in proportion to the height and the antennae are very dark 

A male specimen in the collection (Rio Aravaipa, Arizona, 
2,500 feet) which may be referable to the female has the 
inner hooks suddenly curved forward at their apices. The 
front of this male is noticeably broader than typical australis 

Lucilia australis Townsend. 

Synonym: L. oculata Towasend. 

A large robust species, shining green or blue, showing prac- 
tically no trace of silvery pruinescence, except on head and 

Description based on type specimen, a female. Head in 
frontal aspect distinctly broader than high, gently curved above, 
face somewhat protruding below. Front black, the parafrontals 
overlaid with silvery pollen ; face with brownish tinge, overlaid 
with silvery pollen. Front much longer than broad the third 
antennal joint longer than width of front; frontal vitta twice 
the width of parafrontal; parafrontal but little narrower than 
parafacial. Antennae brownish; arista as long as antenna with 
long and dense plumosity. Facialia with single row of setae 
extending upward one-half its length. Palpi yellow, with scat- 
tered setae. Two post acrostichals. Legs black. Wings slightly 
darkened basally ; basicosta yellow, brownish on mesal margin ; 
squama white, lower one subtriangular. 

Male, — ^The parafrontals contiguous a short distance below 
ocelli, and the parafrontals are much narrowed, so that the front 
at its narrowest width is less than the width of a parafacial. 
Post margin of second tergite with fairly strong bristles. 



Hypopygium ventral, inconspicuous. Outer forceps a little 
curved forward, apex rounded; inner forceps slender, straight. 
Pile on forceps rather dense. 

Length 9-1 1 mm. ; wing 8 mm. 

This is a common woodland species within its range. Speci- 
mens in the collection are from Maryland, Virginia, North 
Carolina, South Carolina, Indiana, Kentucky, Tennessee, 
Georgia, Florida, Alabama, Mississippi and Texas. This 
species was placed as a synonym of caesar. I am indebted to 
Dr. Aldrich for calling my attention to the fact that it is a 
distinct species. 

Lucilia pilatei Hough.

dark blue, without much trace of silvery pollenosity; size 
variable. Description based on part of the original type 

Male , — Head a little broader than high, gently curved above, 
face somewhat protruding downward. Front black, para- 
frontals overlaid with silvery pollen; frontal vilta much nar- 
rowed, the parafrontals nearly contiguous; parafrontal nar- 
rower than parafacial; narrowest width of front greater than 
a parafacial. Antennae a little less than average size, pale 
brown ; arista slightly shorter than antennae. Face, except 
upper parafacial and bucca, yellowish; several irregular rows 
of setae extending half way up facialia. Bucca darkened, with 
black beard on anterior part and pale beard on posterior three- 
fourths. Palpi yellow; with scattered setae. Wings slightly 
darkened; basi-costal yellow; squamae nearly white. Legs 
black. First tergite bluish black ; post margin of second tergite 
bluish black. Outer forceps thin, lamellate ; inner ones slender, 
pointed. Pile on forceps sparse and short. 

Front of female distinctly more narrowed than in sericata, 
somewhat broader than in australis; the width about equal to 
length of third antennal joint. Frontal vitta about twice width 
of parafrontal ; parafrontal but little more narrowed than 

Length 8-10 mm. ; wing 7-8 mm. Represented by specimens 



from Virginia (Virginia Beach), North Carolina (Wilming- 
ton), Georgia (Tifton), Florida (Miami), Mississippi (Pass

Catocha subobsoleta, new species. 

Male — Length 4.8 mm. ; wing 6.4 mm. 

Most closely related to C. americana Felt, from which it 
differs as follows: 

Size larger. Antennae 16-segmented, the basal enlargements 
of the fourth to sixth segments broad, fully one-half as broad 



as long, on the succeeding segments becoming more elongate; 
the apical enlargements of the flagellar segments are indicated 
but are small and setiferous on the outer face. The unique type 
is badly discolored. Mesonotum gibbous, reddish brown with 
two darker brown stripes, the humeral region brightened. 
Mesopleura with the suture between the anepisternum and 
sternopleurite complete. Coxae elongate, especially the fore 
coxae Wings with Sc entire, ending in C a short distance 
beyond r~w; M faint but preserved for its entire length, bend- 
ing strongly toward Rs so r-m is greatly reduced ; vein 2nd A 
becoming entirely obsolete beyond midlength. 

Habitat . — United States (Washington). 

Holotype, c?, l^ongmire Springs, Mt. Rainier, June, 1917 
(H. G, Dyar). 

'Pvpe in the collection of the United States National Museum. 

This interesting gall-midge is distinguished from C. amcricana 
by its larger size and the venational details, especially the 
shortened r-m and the ob.solete apex of vein A. 

Catocha nipponensis, new species. 

Male . — Length 5.5 mm.; wing 8.1 mm.; antenna 7.2 mm. 

Antennae dark brown throughout, the elongate basal flagellar 
segment with the slightly enlarged basal portion more than four 
times the glabrous a])ical pedicel; succeeding flagellar seg- 
ments with the slightly enlarged, this longer than the 
shiny apical pedicel, the latter feebly dilated at the distal end, 
but scarcely nodose. Head dark gray. 

Mesonotum more flattened dorsally than C. subobsoleta: 
sutqre between the anepisternum and stenopleurite indicated 
caudally but the cephalic portion obsolete. Thorax dark brown, 
sparsely pruinose, the praescutum with three blackish stripes. 
Halteres pale brown, the base of the stem brighter. Legs with 
the elongate coxae pale, a little darker basally ; femora brown ; 
tibiae and tarsji brownish black. Wings subhyaline, the veins 
dark brown. Venation : r-m elongate but oblique ; M strongly 
preserved throughout its length, with macrotrichiae ; cell M., 
about two-thirds its petiole; vein 2nd A preserved throughout 
its length. 



Abdomen black, the genitalia paler, brown; dististyles black, 
covered with short hairs. 

Habitat . — ^Japan (Honshiu). 

Holotype, c^, Mt. Minomo, Settsu-no-kuni, November 15, 
1923 (C. Teranishi). 

Dr. Crampton, who has studied the thoracic morphology of 
the above two species of Catocha, considers that the differences 
shown in the shape of the thorax and the individual pleural 
sclerites are sufficient to warrant the erection of a new generic 
group for one of them. 


(Diptera, Culicidae) 

By R. L. turner 
Aedes alleni, new species. 

Somewhat similar to Steyomyia aegypti, but with marked 
differcnce.s in the thorax, tarsi, etc., the thorax being appar- 
ently entirely .silvered (so in front, denuded behind), the tarsi 
with smaller white rings; size larger. The larvae were taken 
from a willow tree-hole on December 28, 1923, at Mission, 
Texas. They were nursed through January, pupated the 22d 
and emerged the 30th, 1924. The thorax of the larvae seemed 
swollen as compared with Stegomyia, otherwise similar. 

Named for Mr. A. F. Allen, Sanitary Engineer. 

Note. — Mr. Turner has sent the two males bred to the 
National Museum. The species is a Finlaya, abundantly dis- 
tinct. The side piece is without hair-tuft at the middle, the 
claspette with small subapical seta. This would throw it into 
the terrrm group, but the coloration of the adult negatives this 
(See Ins. Ins. Mens., vi, 80, 1918). Near triseriatus Say, but 
with ringed tarsi and more silvery on the mesonotum.

{Diptera, Culicxdac) 

By C bonne 

Through the kindness of Mons. Seguy, I had an opportunity 
to examine the type of this species in the Museum of the 
Jardin des Plantes at Paris. The legs have practically dis- 
appeared, body and wings are both badly denuded. One thing 
is very obvious, however, the aMomen ends in a sharp point, 
and it does not resemble at all Culcx quinqucfasciatus Say, 
with which it has been identified. In size and general appear- 
ance it looks like an Aedes or small Psorophora, something like 
Aedes nubilns Theobald. The type is from Conception, Chile, 
South America. 


{/Hptcra, Culicuiar) 


Wyeomyia (Heliconiamyia) chalcoccphala Dyar & Knab, 
The junior author obtained this species in the flower-bracts 
of a Heliconia at Close's Plantation, Cano Saddle, Canal Zone, 
in May, 1923. This is the first record of this species in Panama. 

The larva is very distinct. Mouth-brushes rather short, stout 
and dense. Antennae equalling the brushes, slender, uniform, 
smooth ; a single hair at apical fourth. Frontal spines stout and 
long. Clypeal hairs on the lower part of face forming a curved 
row of three on each side, outer in three, middle in two, inner 
in five. Thoracic hairs in strong multiple tufts, the meta- 
thoracic lateral arising from a large infuscated tubercle. Lateral 
aMominal hairs in threes after the second segment. Comb of 
the eighth segment of many spines in a patch (about 40), the 
single spine blunt-ended and slightly fimbriate. Air-tube con- 
ical, about three times as long as wide ; a pair of 3- to 4-haired 
tufts near the base posteriorly, followed by a delicate fringe 
in about four irregular rows; anteriorly with scattered 2- to 



3-haired tufts in a double irregular row the length of the tube. 
Anal plate with the dorsal angles approximate, each bearing a 
long 3-haired and 2-haired tuft; lateral angles produced, with 
a single long hair; two short stout 5-haired tufts subventrally. 
Anal gills four, long and sack-shaped. 

The figure in the monograph (Plate 92, fig. 296) is inac- 
curate, having been drawn from an imperfect specimen. 

Wyeomyia (Decam 5 da) pseudopecten Dyar & Knab. 

The junior author bred this species from the same species 
of Heliconia as produced chalcocephala, although a different 
individual plant (onidus being associated in smaller proportion), 
and it becomes evident to us what is the identity of galoa, bred 
in Guatemala by H. S. Barber together with chalcocephala, 
Galoa is a synonym of pseudopecten. The bluish lobes and 
whitish hind feet, together with the pale band on the occiput, 
check up exactly. See notes by the senior author on galoa 
(Ins. Ins. Mens., xi, 65, 1923) and on pseudopecten fins. 
Ins. Mens., xi, 170, 1923), to the synonymy of which galoa 
may now be added. 

A |x*culiar occurrence of the larvae of pseudopecten was 
noted, namely, in the flower-sheath of a palm, lying on the 
ground and filled by rain-water, at Cano Saddle, C. Z., August 
11, 1923. Associated with the pseudopecten were other species 
of more normal occurrence in such a situation, namely, 
Wyeomyia {Triamyia) aporonoma D. & K., Wyeomyia 
(Limatus) paraensis Theoh., Culex (Carrollia) secunda B.-W. 
& B., Culex mollis D. & K., Lutzia allostigma H., D. & K., 
Megarhinus hypoptes Knab and Haemagogus sp. $ (probably 
lucifer H., D.*& K.) 

Wyeomyia (Dinom 3 da) phroso Howard, Dyar & Knab. 

The junior author cut down a large “cow’s tongue” Heliconia 
growing on Erwin Island (Barro Colorado Island), C. Z., and 
hollowed out the stump which he filled with water A large 
colony (if the larvae of Culex declarator rewarded his efforts, 
after wl^ich the stump was neglected. Later, on a visit by 
both of tl^e writers, the receptacle was found naturally filled. 



partly by the juice of the plant and partly by rain. The recep- 
tacle now held Sabethids, Phoniomyia chrysomus, Hystatomyia 
circumcincta and Dinomyia phroso. The latter had never before 
been bred, and even now we are not certain of its natural 
habitat. Chrysomus and circumcincta inhabit Tillandsia, but 
phroso has never been bred from this plant. 

However, the very interesting larva was secured. Head 
round, frontal spines long and stout; clypeal hairs low down 
toward the front margin, all four single, a four-haired tuft 
above opposite base of antenna. Antenna exceeding the mouth 
brushes, uniform, smooth, a single hair towards the tip. 
Thoracic hairs moderately stout; lateral abdominal hairs in 
twos after the second segment. Lateral comb of the eighth 
segment of many scales in a patch (about 30), the single scale 
broadly blunt-tipped and minutely fimbriate. Air-tube tapered, 
about two-and-a-half times as long as wide; a posterior band 
of fine fringe-hairs about four rows wide, from near base to 
near apex of tube; on the anterior aspect is a single hair, and 
three more close to the tip. Anal segment half encircled by 
the dorsal plate, the upper angles somewhat produced, approx- 
imate, bearing a long tuft of four and one of two hairs below 
it; at the lateral angle of the plate a long two-haired tuft; 
subventral tufts in fives, rather long. Anal gills four, large and 
bladder-like, equal. 

Sabethinus undosus Coquillett. 

The junior author collected larvae of the species at Porto 
Bello, Panama, in water in bamboo stems. In the monograph 
(Vob iii, page 35) .some doubt is cast upon the predaceous 
habits of these larvae. The senior ‘author, therefore, observed 
this culture with care, and was able to see the use of the long 
maxillae. The larva observed was lying in the bottom of the 
breeding-jar among the sediment, and thrust out leisurely first 
one long maxilla and then the other, gathering into its mouth 
chunks of the sediment. No predaceous behavior was observed, 
and it seems probable that in the original observation of Mr. 
Busck some species of Goeldia was involved, the larvae not at 
the time distinguished from the similar larvae of Sabethinus, 



Wyeomyia (Hystatomyia) coenonus Howard, Dyar & 

The senior author collected larvae from yellow Calathea 
flowers {Calathea insignis Peters) at Gatun, Canal Zone, from 
which female Hystatomyia adults appeared, which we presume 
to belong to this species. The larvae are so similar to those 
of circumcincta (See Monograph, Plate 92, fig. 298) that we 
fail to note any points of difference. The head hairs seem to 
run across in more nearly straight and parallel lines, but this 
may be due to the position of the skin. 

Wyeomyia (Wyeomyia) scotinomus Dyar & Knab. 

We have made every effort to distinguish this species from 
leucopisfhcpus, but seem forced to the conclusion that they are 
the same. The synonymy has been given by the senior author 
(Ins. Ins. Mens., xi, 173, 1923). The name scotinomus has 

The larvae occur in the large smooth-leaved Tillandsia and 
also in the spiny-leaved Hromeliaceae, kindly determined for 
us by Mr. Paul C. Standley as Aechmea setigera Mart. In the 
male hypopygium, the ‘‘core arm’' may l)e free or bent over to 
cross the disk, in which case the end seems pectinate or even 
digitate. This latter condition was supposed to be characteristic 
of scotinomus, and we bred specimens from Aechmea which 
were similar, though less marked. However, another Aechmea 
specimen showed the typical free “core-arm” of leucopisthepus. 
The old material in the collection is not differentiated as to its 
origin as between these two plants, though specimens occur 
both with the arm free and folded over. We are reluctantly 
forced to the conclusion that there is but one species repre- 
sented, the difference in appearance being due to the position 
in^ which the “core-arm” happens to lie. No larval differences 
an\ noted between the Aechmea and the Tillandsia specimens. 

A final consideration seems to clinch the matter, which is 
that^ Phoniomyia chrysomus and Hystatomyia circumcincta 
occur both in the Aechmea and Tillandsia, and also in cultivated 
pineapple, showing that there is no essential difference between 



these plants that would warrant the occurrence of a different 

Wyeomyia (Wyeomyia) homothe Dyar & Knab. 

The junior author collected larvae in a wild pineapple at 
Qose’s Plantation, Cano Saddle, Canal Zone, August 6, 1938, 
which were brought back to the laboratory and bred out by us. 
Wyeomyia homothe emerged, though unfortunately without 
male, and also Goeldia longipes Fab. From an examination of 
the preserved skins, it is evident that Phoniomyia chrysomus 
was also present. It is thought that Wyeomyia rolonca D. & K. 
may be the male of homothe (Dyar, Ins. Ins. Mens., xi, 173, 
1933), but this we were unable to confirm. In regard to 
previous records of occurrence, A. H. Jennings bred a specimen 
from a Bromeliad on a fallen tree; hut one bred by L. H. Dunn 
is marked “tree hole.’* Rolonca was bred from Tillandsia. 
The species probably breeds in various Bromeliads, in the man- 
ner of chrysomus and scofinomus, although it is no longer met 
with in the sanitated parts of the Canal Zone. 

The larva is very similar to that of scotinomus (leucopis- 
thepus). Two skins are before us, both in distorted condition, 
so that it is difficult to make out the arrangement of the teeth 
of the comb of the eighth segment. These appear to be ar- 
ranged in two slightly separated patches with one or two teeth 
considerably detached instead of the long uniform line of

Dr. F. M. Root of the Johns Hopkins Medical School very 
kindly handed me a pair of IVyeomyia from Brazil, which Mr. 
F. L. Soper of the International Health Board bred from 
“water-bearing plants.*' Dr. Root has other specimens. It is 
possible that this species may be one of those listed by Peryassu ; 
but I cannot decide this with any certainty from the published 
descriptions, and consider it best to offer the following char- 
acterization. If this is Peryassu’s wrongly identified Dendro- 
fnyia smithii, as seems most probable from his key, the new 
name is needed anyway. 

Wycomyia mystcs, new species. 

Clypeus nude; postnotum with a tuft of setae posteriorly. 
Head dark scaled, eyes with a continuous narrow white border,, 
joining a large white patch on the side. Prothoracic lobes dull 
violet ; mesonotum dark scaled, the scales on pleura and coxae 
white. Abdomen dark above, whitish below, the colors sep- 
arated on the sides in a nearly straight line, the dorsal color 
projecting slightly ventrally at the posterior angles of the seg- 
ments. Legs entirely dark, the femora whitish beneath. Wing 
scales oval, rather broad, but not extremely so. 

Male hypopygium. Nearest to Dinomyia in structure, but 
of much more elongated form. Stem stout and uniform, less 
than half the length. An expansion about the middle bears a 
spine and seta and a row of five setae along its margin ; within 
this another expansion bears five stout setae. Beyond this, the 
shaft is enlarged, swollen and fimbriate on one side, ending in 
a truncate tip with double point and fimbriate margin. Below 
the double tip are two little filaments and a small rounded knob 
bearing cilia. Still below this, but above the mesial expansion, 
is a double arm, the basal part wide and fimbriate and with a 
small branch, the apical part smooth and curved.

By a. a. GIRAULT 

The following tables, very probably as accurate as may be, 
were made up from type material in the U. S. National 
Museum, but were never subjected to final revision. 

Genus Emersonopsis Girault 

Arizona, Montana. Head as in Pscudomphalc ; sclerite from 
between antennae reaches apex of V-suture in an acute point. 
Parapsidal furrows complete, obtuse, obscure. Scutellum 2, 
submarginal vein 1, bristle or seta. 

Dark green, ab<lomen black, wings clear; tarsi concolorous; venation 
dark. Pedicel slightly longer than funicle 1 ; face glabrous, cross- 
lined below antennae save clypeus, latter with rimmed apex; vertex 
smooth, occiput finely scaly; thorax coarsely reticulate-punctate save 
propodeum whose neck is rugulose; abdomen 2; pronotum and propo- 
deum save groove on each side of meson, glabrous. Male, knees, tibiae 
at apex more or less red, abdomen with long petiole, glabrous; face with 
a hump just below and between antennae, 

(Entedon) cuf>reicoUis (Ashmead) :=r ariconensis (Ashmead) 

Habits unknown. The precedence of the two names had 
not been determined up to the time I left, but can be easily 
done from the literature. 

Genus Amestocharis (Girault 

Australia, North America. The following are species 
referable here for the present: but they bear three (3) ring- 
joints; the male funicle is 3-jointed, club 2-jointed, Head as 
in Pleurotropis. 

Wings clear ; legs concolorous, also scape. Jaws 2-dentate. 
All the species bear two bristles on scutellum and on sub- 
marginal vein. 

Abdomen 2 half the surface, glabrous above, densely scaly beneath, rest 
scaly, abdomen not long ; parapsidal impression glabrous caudad. Sen- 



tellum with more or less distinct median sulcus at base. Median 
carinae of propodeum not very close, diverging distad. Post -marginal 
and stigmal short, subequal. Pedicel a little shorter than funicle 1.

and parallel to marginal vein as in Secodella. 

Ovipositor not extended, the abdomen not stylate. 

Dark green, wings hyaline; scape slightly at base beneath, knees 
broadly, tips of tibiae and the tarsi (except last joint), whitish; 
densely scaly, the propodeum with a median carina. Funicle joints 
twice longer than wide, but 4 a half shorter, longer than pedicel; 
stigmal globular, subsessile, shorter than the postmarginal. Mandi- 
bles tridentate. Scutum scaly-punctate. Discal cilia of fore wing 
more distinct distad elongates Ashmead

The species are, no doubt, associated with Lepidopterous 
larvae. The sparse and inconspicuous discal ciliation of the fore 
wing is characteristic. The cephalic tibial spur forms a strigil, 
is pale and strongly !^-tined {elomjata), Scutellar bristles are 



six ( ?) in elongatus, six minute in marilandicus and none in 
livida. Submarginal with three or more bristles in marilandicus 
and six in livida-

pcrilampoides Girault 


( Di pfera, C ttlicidae ) 


The male genitalia of Culcx iarsalis have never been de- 
scribed. The circumstances were as follows : Both tarsalis and 
stigmatosoma occur around San Francisco, California, and Miss 
Isabel McCracken, collecting there in 1901 for Dr. L. O. How- 
ard, met with stigmatosoma first, and in abundance, owing to 
its habit of breeding in the pools left in river-beds after these 
have gone dry following the disappearance of the rainy season. 
She evidently did not suspect at first that there was a second 
similar sjKicies involved, and the species was identified as Culex 
tarsalis Cckj., from Coquillett’s description. Later she met with 
the true tarsalis in smaller numbers, in permanent water, and 
this form Prof. V. L. Kellogg sent to F. V. Theobald in Eng- 
land as a new species, which Theobald described, naming it 
kelloggii. In making our original studies for the Monograph 
(stigmatosoma was not differentiated until 190?), we failed to 
examine critically Miss McCracken’s material, and followed 



her misidentification of tarsaUs. All the slides which were 
prepared as ^enitalic mounts of tarsalis were made from actual 
specimens of stigmatosoma, and from these the figures and 
descriptions in the Monograph were made. In my subsequent 
papers I failed to detect the error, and was continuously unable 
to separate stigmatosoma and tarsalis by the male hypopygium. 

Male hypopygium of Culrx tarsalis Coq. (California). Lobe 
of side-piece prominent, pilose, with two stout rods and a 
slender one, and a few small setae at base; no leaf, but two 
filaments grouped with the slender rod. Tenth sternites with 
spines on the inner side, but five or six flat teeth on the outer 
side; basal arm strongly recurved, darkly chitinized. Meso- 
somal plate with the horn from base strongly projecting ; inner 
arm very long and strap-shaped, resembling the horn from 
base, pointed; outer arm thumb-shaped; three equal teeth be- 
tween, in the shape of a small claw. 

I have no records of tarsalis from south of the United States 
except just across the border, as at Tia Juana, Mexico. The 
species occurs from California to Texas, reaching the Gulf at 
the Rio Grande, extends northward along the Rockies and east- 
ward to Illinois, and up through the central region to Canada, 
Saskatchewan to British Columbia. The northern limit in the 
west is the Fraser Valley. 

Culex stigmatosoma Dyar. 

Synonyms of this species are Culex eumimetes D. & K. and 
Laiomyia of Izquierdo. The species enters the United States 
on the Pacific where it ranges as far north as San Fran- 
cisco. Also it enters Texas (race thriambus Dyar, diflFering 
in the larva, but with the same habit of breeding in the flood- 
pools in river-l>eds). It is dominant over the Mexican table- 
land, occurs in Guatemala and Costa Rica, and 1 have an un- 
doubted specimen from Venezuela (from the Paris Museum). 
It has not been taken in Panama; but as its occurrence is con- 
ditioned by flood-pools in river-beds, there are prolmbly wide 
gaps in its distribution.

The genera Sabethoidcs and Sabethinus diflFer only in the 
long proboscis of the former. This character is not even of 
subgeneric value in IVyeomyia, and it will be more logical to 
unite these genera, as well as tend to simplify the subject. 
Sabethes differs from Sabethoidcs in the modification ot the 
legs as '‘show-organs.*’ The process begins with the mid legs, 
of which the femora are somewhat elongated as compared with 
the fore femora, and the development of “paddles” of scales at 
the tip of the tibia and basal tarsal joints. The larvae and the 
male hypopygia are similar throughout, as far as known. 
Remipusculus is intermediate in having only the beginnings of 
the paddle-.shaped tuft. These groups seem to be worthy of 
not more than subgeneric value. Greater differences exist be- 
tween the subgenera of Gocldia, Gocldia and Isostomyia.

{Dipt era, Culicidae) 


In originally determining the small Sabethids of the genus 
IVycomyia, the late Fredrick Knab and the writer were not 
familiar with specific limitations, and it now proves that we 
proposed too many names. The probable alternative would 
have been that we would have proposed too few, which would 
have been worse; for synonymy is definite, if a little cumber- 
some, but the difficulties of misidentifications and confusion of 
species are harder to weed out, and often persist almost in- 
definitely in the literature. 

I have noted the synonymy of the Panama forms as deter- 
mined to date (Ins. Ins. Mens., xi, 1(>7, 1923), and will here 
discuss the forms described from Central America and Mexico.

IVyromyia ablechra Dyar & Knab, PriiC. U. S. Nat. Mus., xxxv, 
66 , 1908 . 

From Mexico, Guatemala, Costa Rica and Salvador. The 
coloration and wing-scales is as in homothe of Panama; but 
the single slides show a slight difference in the male hypopygium. 
The difference may not be actual, but due to a partial folding 
back of the “core arm“ of the clasper. In guatemala (See Ins. 
Ins. Mens., vii, Plate v, fig. 8, adclpha), the “core arm” curves 
smoothly along the elliptical tip of clasper, but in homothe (1. c., 
fig. 7, rolonca), it is partly frayed out, and projects down along 
the stem, although it does not actually touch the stem as the 
figure seems to indicate. I have but one slide of the latter, and 
further material may show that but a single species is involved. 
Knab's fine series of ahlabcs, bred in Mexico, was almost totally 
destroyed by museum pests during his illness. 



Wyeomyia homothe Dyar & Knab. 

IVyeomyia homothe Dyar & Knab, Journ N Y. Ent. Soc., xv, 
211, 1907 

IVyeomyia rolonca Dyar & Knab, Proc Ent Soc Wash, xi, 173, 

This species was formerly common in the Canal Zone» 
Panama. Mr. Busck obtained a long series of females at Lion 
Hill, flying in bamboo woods, in 1907. It is now rare, though 
occasionally found on both the Atlantic and Pacific sides. Zetek 
caught a specimen at Balboa in 1913, and Shannon secured one 
at Panama in 1933. Zetek got one at Gatun in 1919 and two 
at Fort Sherman in 1930. Shropshire got one at Monte Lirio 
and two at Cativa in 1931. Shannon found a small series in 
1933 at Qose s Plantation, Cano Saddle, an out-of-the-way 
place up the Trinidad River. 

The larva is described by Dyar & Shannon (Ins. Ins. Mens., 
xii, 89, 1934) ; but probably the comb is not broken as there 
thought, for the structure in guatemala is normal (See larva of 
ablabes, Howard, Dyar & Knab, Mosq. No. & Cent. Am. & 
W. I., ii, Plate 88, fig 381, 1913), and the larvae of the two 
are probably inseparable. 

Wyeomyia abebela Dyar & Knab 

Wveomyta abebela Dyar & Knab, Proc U S Nat Mus , xxxv, 67, 

This species is known only by the series bred by the late 
Fredrick Knab in Mexico. Unfortunately only the male type 
(abdomen on a slide) remains, the other specimens having been 
destroyed by museum pests during Mr. Knab’s last illness. Ac- 
cording to the description, the tarsi of the female are entirely 
dark, which distinguishes the species from celaenocephaia, to 
which it is nearest in coloration. The male hypopygium is very 
distinct (Ins Ins. Mens., vii, 139, 1919).

66, 1908. 

Wyeomyia baria Dyar Knab, Proc. U. S. Nat. Mus., xxxv, 69, 

In this species the wing-scales are broad; prothoracic lobes 
dull dark blue; white on hind tarsi only, the fourth and fifth 
joints being white beneath, but dark at their apices. It thus 
falls next Decamyia, differing in that the white of the tarsi is 
not continuous. From Costa Rica and Salvador, each name 
represented by a single caught female, without data on males or 

Wyeomyia hemisagnosta Dyar & Knab 

Wyeomyia hemisagnosta Dyar & Knab, Jrmrn N Y. Ent. Soc , 
XIV, 230, 1906. 

Founded on a larva found in a cocoanut-husk, Sonsonate, 
Salvador, but not bred. The larva (Howard, Dyar & Knab, 
Mosq. No. & Cent. Am. & W. 1., ii, Plate 93, fig. 303) has the 
hairs single on a rather short and stout tube (the lower double 
one in the figure is an error) ; comb of the eighth segment in a 
narrow patch (in the central part there are in at least one in- 
stance, scales two deep, not shown in the figure) ; dorsal anal 
hairs in 3~2. Evidently on these characters, the adult should 
have broad wing-scales, for the species with narrow wing-scales 
{Wyeomyia) have the anal hairs 1-1. The eighth segment 
has no plate, excluding Pentemyia and Miamyia. The tube has 
no posterior fringe, excluding Calladimyia and Dinomyia. The 
comb-scales arc not few, excluding Limatus and Lemmamyia, 
Triamyia has the anal hairs 4-4, and Hystatomyia has a long 
slender tapering tube. There remains, then, only Decamyia 
with which this larva can be compared. Decamyia, however, 
has false pecten teeth on the air-tube and a broader scale patch 
on the eighth segment, two to three rows deep. A form close to 
Decamyia, but yet different, is gynaecopus, above mentioned, 
and \t seems prohahVe, tYvereiore, iViat Konisagnosta \s \\ve \arva 
of gynaecopus. One of the type localities of gynaecopus 
{baria) is Sonsonate, Salvador, whence the hemisagnosta lar\a 



was obtained. No larva with the characters of hetHisagnosta 
has been taken in Panama, and gynaecopus does not occur in 
Panama. If this circumstantial evidence be taken as conclusive^ 
the name hemisagnosta will take precedence for the species. 

At one time I suggested (Ins. Ins. Mens., vii, 140, 1919) 
hemisagnosta might be the larva of Lemmamyia; but that has 
since been found, and proves to be quite different (Ins. Ins. 
Mens., xii, 90, 1924). 

It is probable that when the male is found it will represent a 
separate subgenus. 


(Diptera, Culicidae) 


The Sabethid mosquitoes are not represented by many forms 
in the West Indies. Apart from one predaceous form {Gaeldia 
perturbans Will) and another (Sabethcs bipartipes D. & K.), 
possibly also predaceous, the sjDecies all belong to Wyeomyui 
(sensu lat.). Names have been proposed for each species on 
each separate island, and while it is possible that each island 
has a separate form or race, there is nothing to indicate it in 
the information so far at hand. The species and insular forms 
arrange as follows: 

Prothoracic lobes larger, more or less approximated dorsal ly. 

Wing scales narrow. 

Prothoracic lobes silver scaled. 

Mid and hind tarsi white-marked. 

vanduzeei Dyar & Knab Florida 

f rater cuia Dyar & Knab Martinique

Mid tarsi with paddles. 

bipartipes Dyar & Knab Santo Domingo

perturbans Williston St. Vincent 

In regard to the subgeneric station of the species, vanduseei 
and presumably bahama (its male is not yet known) belong to 
Dendromyia as used by me (Ins. Ins. Mens., vii, 124, 1919) ; 
mitchellii and pertinans belong to Wycomyia proper {grayii is 
the genotype) ; grenadensis belongs to Dodecamyia. 

Wyeomyia vanduzeei Dyar & Knab. 

From Florida, Cuba, Santo Domingo and Martinique. It 
has not been taken in Jamaica, nor in the Virgin or Leeward 
Islands. No continental species is known with the prothoracic 
lobes all silvery scaled. The larvae live in the water at the 
leaf-bases of epiphytic Bromeliaceae. 

Wyeomyia bahama Dyar & Knab. 

The species inhabits the eastern tip of Cuba and the Bahamas. 
The larva and life history as well as the male are unknown, but 
all are probably as in vanduzeei or closely similar. This seems 
to be a derivative species of vanduseei , the distribution being 
the same as between Aedes condolescens D. & K. (Cuba and 
Bahamas) occurring alone in the Bahamas, but associated with 
Aedes scapularis Rond, in Cuba, as Wyeomyia bahama occurs 
alone in the Bahamas, but associated with vanduseei in Cuba. 



Wyeomyia mitchellii Theobald. 

From Florida, Cuba, Santo Domingo, Jamaica and Dcaninica, 
not taken in the Bahamas, Virgin or Leeward Islands, of which 
the two latter groups seem to be bare of Sabethids. Two names 
were proposed for the Santo Domingoan form, ochrura founded 
on the larva and glaucocephda on the adult. The white spots 
at the bases of the hind tarsal joints are very variaUe, some- 
times very large, sometimes minute or absent, the variation be- 
ing independent of locality, as great a range occurring in 
Florida as in Santo Domingo. The larvae live in the leaf bases 
of epiphytic Bromeliaceae, both this species and vanduseei oc- 
curring together in the same plants. 

Wyeomyia pertinans Williston. 

From St. Vincent and St. Lucia, apparently confined to the 
Windward Islands. Bonne- Wepster and Bonne have described 
the male (Ins. Ins. Mens., ix, 10, 1921). The larvae are prey^ 
upon by Goeldia perturbans Williston, but the habitat is not 
definitely stated. 

Wyeomyia grenadensis Edwards. 

I have referred this to the synonymy of clasoleuca D. & K. 
(Ins. Ins. Mens., vii, 139, 1919), and Bonne-Wepster & Bonne 
say that this is probably correct (Ins. Ins. Mens., ix, 10, 1921). 
In their list of the mosquitws of Surinam (Ins. Ins. Mens., xi, 
123, 1923), Bonne-Wepster & Bonne record clasoleuca from 
Surinam; but apparently they had females only, and they re- 
described the same form as Dendromyia roucouyana (Ins. Ins. 
Mens., vii, 166, 1920), again from females, although with the 
larva. Thus the corresponding male from Surinam is not 
known, and the male of grenadensis is also unknown. Until the 
males are known, the synonymy must remain uncertain; but 
grenadensis is doubtless a Dodecamyia, and probably the same 
as clasoleuca^ 1 do not believe that it is an endemic form. 

The larva (according to Bonne-Wepster & Bonne) lives in 
Bromeliaceae, having an air-tube of the Hystatomyia type, but 
single comb of the eighth s^^ent, 12 large scales in a straight 



Sabethes bipartipes Dyar & Knab. 

The occurrence of a Sabethes in the West Indies is unex- 
pected ; but we have two records from Santo Domingo (Camp- 
bell and Busck). The species has been taken in Ecuador, Suri- 
nam and British Guiana. Doctor and Mrs. Bonne found pupae 
in rather clear water held by a fallen banana-leaf, associated 
with Limatus and Lemmamyia, and again in water in a hole in 
a fallen tree. They say that the larvae are predaceous (Ins. 
Ins. Mens., ix, 98, 1921) and were feeding on several species 
of Culex, and even on Uranotaenia lowii, as the water contained 
many green algae in the latter case. We do not feel certain 
of the predaceous habit, in spite of Dr. Bonne’s apparently 
positive statement, for Sabethinus undosus, with identical 
mouth-parts, is certainly not so. The statement may possibly 
mean no more than that the Sabethes occurred with the others. 
Positive observations on this point are desirable, as the larva 
of no other species of Sabethes is known. 

Goeldia perturbans Williston. 

Predaceous as larva upon Wyeomyia pertinans Will, in St. 
Vincent. This is an apparently endemic form, peculiar to the 
Windward Islands, it> nearest relative being Goeldia homotina 
D. & K,, recorded from Panama and Surinam. 


{Diptera, Culicidae) 

Phoniomyia Theobald. 

The identification of this Sabethine genus is becoming ob- 
scure. Theobald restricted his genus IVyeontyia (Mon. Culk., 
iii, 310, 1903) to grayii and pertinans (which are doubtless 
synonyms), and erected the genus Phoniomyia for longirostris 
and aranoides. The former has been fixed as the type. 

Theobald described Wyeomyia longirostris (Mon. CuHc., ii, 
275, 1901), and at the time of erecting Phoniomyia, he made 
trinidadensis (Mon. Culic., ii, 277, 1901) a synonym thereof. 



Bonne- Wepster and Bonne discuss these species (Ins. Ins. 
Mens., ix, 6~8, 1921), and in regard to longirostris, they found 
the types to consist of a female and a male. They restricted 
the type to the female, and determined the male to belong to 
Theobald’s trinidadensis ; but it is not clear whether this male 
was from Trinidad or Brazil. Theobald does not mention a 
male nor a specimen from Trinidad in his description of 
longirostris, but did have more than one specimen from Dr. 
Lutz, all “more or less damaged.” Therefore I think that 
Bonne-Wepster and Bonne should not have identified the male 
longirostris with trinidadensis on account of the discrepancy in 
locality. Their restriction of the type of longirostris to the 
female must hold, unfortunately as it now appears. 

The male specimen, now rejected as type, is a Dodecamyia 
from Brazil, probocis long, abdominal colors incised, mid tarsi 
with white on the second to fourth joints, hind tarsi with basal 
parts of fourth and fifth joints white. This corresponds with 
the Mana type of qiumlongirostris Theob. (Mon. Culic., iv, 
598, 1907), of which the specimen is probably the male; but it 
leaves trinidadensis without a known male. 

The type of Phoniomyia, then, is a female with long probocis 
and broad (so stated) wing-scales, the abdominal colors sep- 
arated in a straight line. The color of the tarsi is unknown. 
Theobald does not mention any white, but the male which he 
had before him and which he used in describing the abdomen 
has white marked tarsi, and it is probable that he overlooked 
this character in the early part of his work. 

This renders the identification of Phoniomyia sufficiently ob- 
scure. The long proboscis, far from being of subgeneric value 
in Wypomyia as Edwards has supposed (Bull. Ent. Res., xiii, 
76, 1922), occurs in Dodecamyia (but not all the species), in 
Dyarina and in my use of Dendromyia (Ins. Ins. Mens., xi, 66 
and 172, 1923). 

Most probably Phoniomyia is a Dodecamyia with long pro- 
boscis and abdominal colors separated in a straight line, but 
with broad (so stated) wing scales and from Brazil. Theobald 
figures the wing-scales of longirostris, female (Mon. Culic., Hi, 
Plate XV, 1903). The end of the cell is shown, but not the 


3 09 

bases of the fork-cells. The appressed scales are narrowly tri- 
angular, the outstanding ones sparse and narrowly ligulate. 
Theobald used the terms “broad” and “narrow” somewhat 
loosely. In describing those of Phoniomyia as broad, he evi- 
dently referred to the appressed scales, whereas it is the out- 
standing ones that we are accustomed to regard as diagnostic.^ 
An appearance almost identical with Theobald’s figure is pre- 
sented by Dodecamyia aphobema, and presumably by bodkini 
also, although this is not before me. In case either of these 
species shall be found to extend its range to Brazil, the identity 
of longirostris will be solved. In any case it must be a repre- 
sentative species of these, and Phoniomyia will replace Dode-

Leontiniae is from Argentina (Bol. Inst. Ent. y Pat. Veg., 
41, 1912), tripartita from Brazil, and fuscipes from Paraguay. 
I suspect that they represent one species, although the male is 
known only of tripartita. In that, the tenth stemites have six 
teeth, the ninth tergites with the spines less than twice as long 
as the prominence. 

Dendromyia Theobald. 

Theobald proposed the genus Dendromyia (Mon. Culic., iii^ 
313, 1903) without specifying the type, including five species, 
ulocoma, asullepta, paraensis, quasiluteoventralis, and luteoven- 
tralis. In the description he says it differs from Phoniomyia in 
the much shorter proboscis and more densely scaled wings, and 
makes reference both under the generic heading and specifically 
in the text to Plate XV, showing the broad scaling of Den- 
dromyia ulocoma. In spite of this plain indication of which 
species Theobald considered typical of his generic conception, 
Blanchard (Les Moust,, 426, 1905) specified luteoventralis as 
the type. Under the rules, this specification must hold. 

Wyeomyia luteoventralis (Mon. Culic., ii, 348, 1901) was 
founded on three females from Para, Brazil. The wing scales 
are said to be broad, resembling those of Goeldia lunata; ab- 
dominal colors separated in a straight line ; no white mentioned 
on tarsi; proboscis presumably not long; first abdominal seg- 
ment bright testaceous, a few scales showing violet reflections* 
The color of the prothoracic lobes is not mentioned. 



Later (Mon. Culic., iii, 318, 1903), Theobald adds several 
new localities, British Guiana, Trinidad, Sao Paulo, Brazil, and 
gives a figure of a wing showing typical narrow outstanding 
scales. He also describes qmsihiteovcntralis from British 
Guiana, diflFering (only?) in the relative lengths of the “hind 
metatarsi and tibiae.’’ Blanchard (1905) made the two names 
synonymous ; but this added material, possibly not all conspecific, 
so confused the subject that Doctor Howard’s subsequent notes 
are indecisive. Doctor Howard reports, his report covering 
both Itifcovenfralis and quasiluteoz^cntralis (Mosq. No. & Cent. 
Am. &: W. I., iii, 71, 1915) : “Prothoracic lobes with purplish 
coppery scales; middle tarsi with the three terminal joints 
whitish.” In this place, Howard, Dyar and Knab consider 
lutcoventralis as near the Panama chrysomus, and this idea was 
followed out by me in subsequent subgeneric work in my use 
of Dendromyia (Ins. Ins. Mens., vii, 124, 1919; xi, 65, 172, 
1923). Doctor and Mrs. Bonne report (Ins. Ins. Mens., ix, 11, 
1J121) : “The legs are unbanded; median distinct white line on 
occiput ; colors of the abdomen separated in a straight line ; 
])rothoracic lobes with coppery tips.” 

Unfortunately Doctor and Mrs. Bonne do not specify the 
shape of the outstanding scales at the base of the fork of 
second vein. It would seem that these are broad. Theobald’s 
reference to Dendromyia may not be decisive; but Doctor Lutz 
a})parently recognized the species, for in Peryassu (page 74) 
he gives, besides Theobald’s original locality, Para, also “Sao 
Paulo (Lutz).” Doctor Lutz carefully distinguished the genera 
on the characters of the wing scales, using the outstanding ones 
as diagnostic. In the Bourroul paper, he separates Phoniomyia 
(properly Dyarina) and Wyeomym on this character, placing 
Dendromyia in the broad scaled section, and in the Peryassu 
paper he repeats the separation, adding Mcnolepis to the nar- 
row scaled section (page 38). In the description of luteoven-^ 
traits (page 305), the scales are described as “rather large,” 
which sounds like a translation of Theobald’s original. Pery- 
assii states that he emended and corrected Theobald’s descrip- 
tions “in most cases ;” but apparently this description was not 



SO corrected. Anyway, Doctor Lutz apparently thought to 
recognize luteoventralis in a broad scaled form. 

No species with these characters is known to me, and it may 
be that luteoventralis remains to be rediscovered. Until this 
is done and the male made known, the proper application of 
Dendromyia perhaps cannot be made. 

In any case, my use of Dendromyia is invalidated, and for 
the group which I treated under this name I propose the sub- 
generic name Phyllozomyia, type smithii Coquillett, the 
other known forms being chrysomus D. & K. of Panama, and 
the West Indian species with silvery prothoracic lobes, of which 
only vanduzeei is known in the male. 

In regard to the other species placed originally in Dendrom- 
yia by Theobald, paraensis has been referred to Limatus 
f Bonne- Wepster & Bonne, Ins. Ins. Mens., ix, 6, 1981) and 
asullepta to Lemmamyia (1. c., 6). Both of these species have 
narrow outstanding scales at the base of the fork of second 
vein, although the scales outwardly are distinctly broad, which 
has a bearing on the statement that the scales of luteoventralis 
are broad. 

The identity of utocoma has not been positively fixed. It 
was described from British Guiana. I suggested that it might 
be Cleobonnea occulta (Ins, Ins. Mens., vii, 134, 1919); but 
Bonne- Wepster and Bonne pointed out that this could not be 
the case (Ins. Ins, Mens., ix, 10, 1981). They considered the 
species unrecognizable; but a broad scaled species with dark 
tarsi and lobes essentially the color of the mesonotum would 
fit very well in Decamyia, The Decamyia lobes have a slight 
blue tint, but not marked unless looked for, so that we de- 
scribed the lobes as the color of the mesonotum in the Mono- 
graph. Of the three Decamyia. which all extend from Panama 
to Trinidad, pseudopeefen has a distinct whitish stripe on the 
occiput, which is stated to be absent in the original description 
of ulocoma. This stripe, however, is not visible or very faint 
in most specimens of onidus and eloisa, either of which species 
would fit ulocoma. It is next to impossible to choose. 'The 
specin^ens were taken by Dr. Low in the forest near Demerara' 
River twelve noon in subdued light.” Onidus lives in the 



led-flowcred Heliconia (Bihai), while eloisa lives in the yellow- 
flowered Calathea, Either or both of these plants may have 
been growing in the vicinity of the collecting ground. 

According to Doctor and Mrs. Bonne (Ins. Ins. Mens., ix, 
11, 1921), only a female specimen is present in the British 
Museum collection to represent quasiluteoventralis, from a dif- 
ferent locality from any of the three mentioned in the original 
description. They say that this female may be Wyeomyia 
oblita Lutz, a species with narrow wing-scales, as to the out- 
standing ones, though the appressed ones outwardly are rather 
broad. Theobald says : “Wings with broadish brown scales on 
the forks and on the third long vein.” There is nothing here 
to contradict the reference to oblita Lutz, or rather fallax 
B.-W. & B., since T think that their reference of their species 
to oblita is scarcely justified. The discrepancy in locality is too 
great, as the other species of Wyeomyia are distinctly local. 
However, quasiluteoventralu is doubtless fallax, and a definite 
reference of it may be made. 


{Ihptera, Culicxdac) 


Further study has reduced the probable number of good 
species existing in Wyeomyia proper. In first listing this group 
as a subgenus (Ins. Ins. Mens., vii, 127, 1919), twenty-seven 
species were recognized on adult coloration. The character 
used by Doctor A. Lutz (in the papers by Bourroul and Pery> 
assii) of the narrow outstanding wing-scales is characterisiic 
of the subgenus, although other subgenera possess it also. The 
claspers of the male hypopygium have a long slender stem, not 
existing in the other groups. Three types of clasper-tip exist. 
In the first, the tip is triangularly distorted, one angle drawn 
backward and ending in a flat plate that looks like a hole, a 
spine on the other side tied to the main body of radiating 
ligaments. This type occurs in but one species, ahebela of 



The second type of clasp tip is triangularly expanded with a 
short arm on either side, a row of setiferous tubercles through 
the middle ; a fourth pilose arm, the ‘"core arm,” lies across the 
disk, or may be displaced. The main disk is squarely ended, 
as shown in the species scotinomus and camptocomma, or one 
angle may be produced, carrying another row of setae, as in 
qimsUuteoventralis, pertinans and mitchellii. 

In the third type, the tip forms a bud-shaped mass, either 
with a short arm on either side as in gmiemcda, or with these 
armis absorbed, as in simmsi and melanopus. 

The species differ in the coloration of the legs; but these 
differences in coloration do not run parallel to the male geni- 
talia, but rather traverse of them. A combination of the two 
sets of characters separates the species as follows: 

Tarsi alt dark.

ceding, page 102.

Wyeomyia melanopus Dyar. 

I made the suggestion (Ins. Ins. Mens., xi, 173, 1933) that 
this might be the male of celaenocephala from Central America 
and Panama ; but I now consider this to be unlikely. There is 
no trace of white on the mid tarsi, the specimen being in good 
condition. The other species do not differ sexually in this 
manner. Moreover, the proboscis in melanopus is very long 
and slender, not corresponding with that of celaenocephala, 
which is shorter than the abdomen. I will therefore hold this 
species apart on the single male type pending the receipt of 
further material.

The tip of the male clasper is of the type of quasiluteoven- 
traits, but differs in detail. The production of the corner of 
the disk is more lateral and angular. There are a j>air of finger 
shaped proce.sses on top of the mesosomal appendages, not on 
the “harpes’’ (tenth sternites) as slated by me in proposing the 
subgenus Diphalangarpe on this character (Ins. Ins. Mens., vii, 
13G, 1919). The slide of ahascanta, which was mislaid at the 
time of writing, has now been found. It agrees with telestica 
in these characters, except that, being more strongly pressed, 
the finger-shaped processes are more prominent. The structure 
does not seem to be present in quasiluteoventralis. The species 
is from Trinidad, and identifications of telestica from the main- 
land ( Bonne- Wepster & Bonne, Ins. Ins. Mens., xi, 134, 



1923; Edwards, Bull. Ent. Res., xiii, 80, 1922) are probably 

Wyeomyia oblita Theobald. 

Dendromyia obltia Theobald, Mon. Culic., iv, 612, 1907, 
Dendrontyia medioalbipes Peryassu, Os Culic. do Brazil, 303, 1908. 

This is the Brazilian form corresponding to qiMsUuteoven- 
traits and telestica, and doubtless, when males are at hand, it 
will prove to be specifically distinct.

This is the corresponding form from Panama and Central

male is known ; but I now think that it will prove to be of the 
type of quasiluteoventralis, though specifically distinct.

on larval characters as well (Ins. Ins. Mens., xi, 173, 1923). 


(Dtptera, Culictdae) 


In treating of this group recently (Ins. Ins. Mens., x, 51-60, 
102^), I was unable to give a table for separation of the species 
by the male genitalia. As between the major species, this prob- 
ably cannot be done ; but as between the minor species, certain 
differences appear, and I am now inclined to regroup the forms 
from the arrangement used in that paper, and to give specific 
rank to some forms that I considered racial. A subgeneric 
name is available for this group, if desired, namely Pseudo- 
howardina Theobald, type trivittatus Coq. 

Aedes obturbator Dyar & Knab. 

No additional information is available about this form. 
Aedes trivittatus Co(iuillett. 

In the typical form from the United States, the claspette 
filament is normally and slenderly inserted on the stem, the 
spine on the basal lobe of the side-piece is moderately stout and 
the setae on the lobe rather long. The form is confined to the 
United States as far as my material shows. The only synonym 
is inconspicuus Smith & (irossbeck 

Aedes angustivittatus Dyar & Knab. 

In the specimens from Mexico, Costa Rica and Panama, the 
filament of the claspette is short and inserted in a cup-shaped 
expansion at the tip of the stem ; the spine of the basal lobe is 
much stouter. I am therefore inclined to give this form specific 
rank, with cuneatus D. & K. and argentescens D. & K. as 
synonyms. In the type of angustivittatus the yellow lines of 
the mesonotum are narrow and straight, while in the other 



named forms they are irregular and widened ; but the marking 
is inconstant, and I think the differences are due only to varia- 

Ai^es thelcter Dyar. 

The characters of this species are fairly distinct. The lobe 
of the side-piece is raised and prominent, with all the setae on 
the terminal aspect ; the spine is situated at the base of the eleva- 
tion, and is small in comparison with the usual state. The 
retrose spine of the filament of the claspette is reduced, only two 
little points showing. 

Fresh material of the species has been received from Browns- 
ville, Texas, through Mr. R. L. Turner, collected February 12, 

Aedes scapularis Rondani. 

This is the tropical continental form, which is before me 
from Argentina, Brazil, Bolivia, Trinidad, British Guiana, 
Venezuela, Colombia and Ecuador. The abdomen of the female 
is black above, with a more or less distinct dorsal median dull 
violaceous whitish stripe. In the male hypopygium the basal 
lobe is very small, the setae few and short, not a quarter the 
length of the rather slender spine Synonyms are confirmatus 
Lynch and camposanus Dyar. The claspette filament has a 
minute retrose spine or only a slight notch, sometimes hard to 

Aedes scapularis hemisunis D\ar & Knab. 

The Antillean form, which I have from Santo Domingo, 
Jamaica and Cuba (but males only from Jamaica), has been 
considered as the same as scapularis; but in the male the setae 
of the basal lobe are more numerous (16-20; about 10 in scap- 
ular is') and the spine is slightly stouter; on which characters a 
race seems indicated. A synonym is indolecsens D. & K. 
(Cuba; no mile before me). 

Aedes euplocamus Dyar & Knab. 

I am inclined now to rate this as a species instead of a sub* 
spedes as in my former paper. In the male, the setae on the 



basal lobe are much longer, some of them reaching nearly to 
the tip of the spine, while the spines of the ninth tergites are 
also elongated. This, together with the larval differences noted, 
seems to indicate a species. The form is before me from 
Mexico, Costa Rica and Panama, the latter locality being a 
correction of former identifications. It is euplocamus which 
occurs in Panama and not scapularis as formerly supposed by 
me (Ins. Ins. Mens., xi, 181, 1923). A male has recently been 
submitted to examination, Bella Vista, Canal Zone, June 3, 
1922 (J. B. Shropshire). Heretofore neither male nor larva 
from Panama had been under observation. 

Aedes infirmatus Dyar & Knab. 

This form also I am now inclined to rank as a species. In 
the male hypopygium, the spine is extraordinarily stout. The 
setae of the basal lobe are long, much as in euplocamus; but 
this peculiar spine, together with the larval differences, seems 
to indicate specific rank. 

Aedes condolescens Dyar & Knab 

Males of this form are now before me, and a distinct species 
is indicated. The basal lobe of the side piece is distinctly 
projecting, with rather long setae, the spine is stouter than in 
scapularis, and the filament of the claspette is widely angled 
with two to six retrose spines instead of the single and often 
obscure one of scapularis. The species is distinct on adult 
coloration, having transverse white basal abdominal bands. It 
is before me from the Bahamas, where it occurs alone, and 
Cuba, where it is less abundant than scapularis hemisurus. 

Concerning the forms of tortilis, lynchii and crinifer, there 
is nothing to add at present. 


(Dipt era, Culicidae) 


Major L. H. Dunn has sent me a number of mosquitoes from 
Colombia which he met with in his work against the outbreak 



of yellow fever there. He has kindly allowed me to describe 
the new forms among them. The mosquito fauna of tropical 
America is little known. There are a few exceptions, such as 
Brazil, where a number of able resident workers have studied 
the subject; Trinidad and British Guiana, through the re- 
searches of Urich, Moore anl Bodkin; Surinam, through the 
excellent work of Doctor and Mrs. Bonne; Panama, through 
the American workers ; and the Antilles, through Busck, Grab- 
ham, Pazos and Coffin. The present locality, Colombia, touches 
an unexplored spot. In a former paper (Ins. Ins. Mens,, x, 
192-194, 1922), I described three species from Colombia, Cidex 
{CarroUia) paraplesia (—Acdinus amasonensis Lutz), Aedes 
euiris, and A 'cdes milleri. None of them occurred in the present 

Wyeom 3 da (Wyeomyia) camptocomma, new species. 

Wing-scales narrow; prothoracic lobes of the color of the 
mesonotum ; colors of the abdomen separated on the sides in a 
straight line; mid tarsi with the tip of the second, the third to 
fifth joints white below ; hind tarsi with the base of the third, 
the fourth and fifth white below, the white broadly interrupted 
at the tip of fourth joint. 

Male hypopygium. Side piece three times as long as as wide, 
uniform, the tip narrowed and roundedly bent at right-angles. 
Clasper with a long and narrow stem, three-fourths as long 
as the side-piece, the tip broadly expanded as in scotinomus of 
Panama. The details differ from that species : The longer side 
arm is very stout, forming a broad bulging shoulder, while the 
.smaller arm is folded over on the disk, hook-shaped and slightly 
fimbriate; the core-arm forms a large fimbriate pad, folded 
across the disk. Base of side-piece with three approximate 
setae. Tenth sternites simple, long, with dentate tip; second 
pair of appendages (mesosome?) shorter, stouter, with pointed 
tips. Ninth tergites with two stout spines on each side. 

Larva. Head round; frontal hairs along anterior margin, 
one, two, three ; a multiple tuft below base of antenna on the 
under aspect; a small tuft within the eye. Thorax quadrate j 
abdomen long, uniform; long lateral hairs double on fourth 



and fifth segments, single on sixth and seventh; short hairs in 
tufts of three and four; comb of the eighth segment of many 
scales in a straight even line; air-tube moderate, about four 
times as long as wide, subfusiform, tapering outwardly; two 
basal hair-tufts double, the others single and coarse, no hairs 
on the outer fourth of the tube. Anal segment with two long 
hairs on each side at the dorsal angles, a single lateral one; 
subventral tuft small, multiple (in 12). 

Five males, ten females and many larvae, taken from the 
bases of the leaves of elephant’s ear plants (Calladtum), Bar- 
ranquilla, Colombia (L. H. Dunn). 

Culex (Culex) aglischrus, new species. 

Proboscis with a white area beneath, which sometimes shows 
slightly above ; mesonotuni brown, frequently with two whitish 
spots behind the middle; abdomen black, with narrow basal 
segmental white bands; tarsi with narrow white rings at both 
ends of the joints ; wing scales dark. 

Male hypopygium. Side piece stout, the lobe at the middle, 
at the apex of the basal excavation, long, slender, bearing three 
long stout rods with curved tips, the middle one weaker and 
shorter; a few setae on the lobe, continuous with the general 
vestitnre (Plate IV, fig. 4). Clasper stout, with moderate in- 
serted terminal spine. Tenth sternites large, with very long 
basal arm, but weakly chitinizcd, pale, with many short fine 
spines at tip and an unusual number of long setae on the side, 
Mesosome with the outer arm thick, shoulder-like, the lower 
stoutly thumb-shaped, denticles fine and appressed, scarcely 
separable, crowned by a delicate double hook ; tooth very large 
and long, exceeding the body of the mesosome by half its 
length, slightly bent and with a mesial ridge running from the 
tip (Plate IV, fig. 3). 

Larva. Head wider than long, widest through the eyes; 
antennae long, a tuft at the outer third, the part beyond some- 
what more slender. Head hairs in fours, the tuft before the 
antennae multiple. Comb of the eighth segment of about 24 
scales in a patch, sparsely placed. Air-tube straight, slightly 
tapering, about four times the length of the width at base; pilose 


posteriorly beyond the middle, the pile becoming strong and 
abundant at the tip all around; pecten long, reaching over a 
third of the tube ; hair tufts of four pairs, all beyond the pecten, 
pressed back posteriorly and irregular in alignment. Anal seg- 
ment ringed by the plate, the ventral brush posterior; dorsally 
a long hair and a tuft on each side. Anal gills four, shorter 
than the segment. 

Types three males and three females, selected from a series 
of 80, bred from a hole in the ground and a deep hole resem- 
bling a shallow well, Barranquilla, Colombia (L. H. Dunn). 
Also captured adults, Bogota, Apulo and Puerto Berrio, Colom- 
bia, during the season of 1923. 

This species is obviously ancestral to Culex coronator, both 
on genitalic and larva! characters. The coloration is much the 
same, but the specimens run larger, and the little light dots on 
the mesonotum are often characteristic. Since the adults were 
taken among hand catches, it is probable that the female bites. 
It appears that coronator has lost the habit of biting warm- 
blooded animals, for it did not occur among the hand-catches in 
Colombia, though Major Dunn found it one of the commonest 
as larva. 

The m,esosomal plate of the male hypopygium of the allied 
species of the coronator group is shown on Plate IV. These 
all have the tenth sternites membranous and thin, and no leaf 
on the lobe of the side piece, or merely a rudimentary one. The 
group seems to have branched off from farsalis, by the degenera- 
tion of the tenth sternites. In tarsalis, the tenth sternites are 
normal, though the lobe of the side piece is without a well de- 
veloped leaf as in these. 

Aglischrus is the most primitive in regard to the lobe of the 
side piece (Plate IV, fig. 4), which hardly differs from the 
condition in Lutsia. The mesosomal plate, however, is special- 
ized, the disk reduced, but the horn from the base hypertrophied 
(Plate IV, fig. 3). In surinamensis and coronator, the struc- 
ture is well developed; but whereas in surinamensis (Plate IV, 
fig. 2) the upper arm of the plate is shorter than the teeth, in 
coronator (Plate IV, fig. 1) it exceeds them. In brevispinosus 
(Plate TV, fig. 7) a quite different shape is given to the plate, 



the upper arm being capitate, the lower rudimentary, while the 
horn is only moderately developed. 

In duplicator (Plate IV, fig. 5) and honneae (Plate IV, tig. 
8), the plate is curved and composed of close denticles as is the 
case in corniger: but cornigcr has the tenth sternites normal 
and a well developed leaf on the lobe of the side piece, which 
would place it in another group. In duplicator, the horn takes 
the form of a triangular plate. The lobe of the side piece is 
simple (Plate IV, fig. 6), except for two little hair patches. 
Duplicator is found only in Santo Domingo, where Mr. Busck 
obtained it in 1905. We were pleased to receive recently fresh 
material from Port-au-Prince, Haiti, from Lieut. E. Peterson, 
no specimens of this form having come to hand in the inter- 
vening nineteen years. 

Culex (Choeroporpa) sursumptor, new species. 

Occiput dark brown, the scales oval, not very broad, but this 
type reaching the vertex. Mesonotum bronzy brown. Abdomen 
black, with basal segmental white hands, joining spots on the 
sides. Tarsi dark. Wing-scales dark, narrow on the base of 
the fork of second vein, becoming oval toward the tips of the 

Male hypopygium. Outer division of the lobe of side-piece 
with a short but distinct inner arm; middle filament and the 
four on the outer aspect forming a single group. Inner divi- 
sion closely approximated to the outer, strongly forked, bear- 
ing two twisted filaments with bent tips. Tenth sternites comb- 
shaped, slender; mesosome reduced to a stout hook on each 
.side, exceeded by the recurved, spatulate-tipped basal hooks; 
ninth tergites a pair of elliptical setose pads. 

Types, three females and a male, bred from a pool, Barran- 
(piilla, Colombia (L. H. Dunn), but no larvae were preserved. 

Culex (Choeroporpa) ligator, new species. 

The head and mesonotum are darker brown than in the pre- 
ceding form, but there are no positive diagnostic colorational 
characters between the two. 



Male hypopj^ium. Side piece as in the preceding; a seta at 
extreme base of outer division of lobe. Tenth sternites flattened 
comb-shaped, long. Mesosomal plate narrowed toward base, 
the arms stout and bluntly pointed, one erect, the other at nght 
angles; third point small, sharp, directly opposite the lower 
arm. Basal hooks recurved, but short, not reaching middle of 
mesosomal plate. Ninth tergites rather large, rounded tri- 
angular pads, setose. All much as in iolambdis Dyar, but in 
that the upper mesosomal arm is short and dentate, and other 
differences in detail. 

Larva. Head elliptical, wider than long, not widened at the 
eyes, infuscated with brown except on the margins; antennae 
long, notched beyond the middle, with a large tuft, the terminal 
third infuscated. Frontal spines very stout; long head hairs 
single, with a small two-haired tuft above and minute single 
hair within, tuft near antennae long and large, multiple, the 
structure normal for Choeroporpa (see Monograpdi plates 10") 
and 10 ( 5 , figs. 349 , 351 , 353 , 351 and 355 ). Body pilose through- 
out, the pile weaker posteriorly. Comb of the eighth segment 
of many spines in a large patch. Air-tube about five times as 
long as wide at base, evenly tapering ; pecten to one-third ; six 
pairs of posterior hair-tufts, the l)a.sal one just within the end 
of the pecten and the longest and, feathered, the others 
progressively shorter; tube glabrous, the extreme base infus- 
cated. Anal segment about as broad as long, ringed by the plate ; 
ventral brush posterior; dorsal hairs a long single one, and 
another double one, of which one segment is long and stout 
and the other weaker. Anal gills longer than the segment, 

Types, two females and one male, bred from a pool in a 
stream-bed that was nearly dry, Barranquilla, Colombia (L. H. 
Dunn). Anopheles pseudopunctipennis Theob. and Culex 
(oronator D. & K. were associated. 




(Diptera, Culicidae) 

Culex badgeri, new species. 

Head with narrow curved golden brown scales of the usual 
type ; a small patch of black scales on the side, below which the 
scales are flat and appressed, whitish brown; mesonotum with 
the scales fine and small, appearing sparse, shining golden brown 
as on the head, lighter than the dark brown integument. Ab- 
domen black above, the segments dull yellowish toward their 
bases, forming a very indistinct paler banding; venter immac- 
ulate, light brown scaled. Legs black, femora pale beneath, 
tips of femora and tibiae indistinctly and narrowly light brown. 
Wing scales hair-like. In the male there are some white scales 
on the palpi beneath, chiefly at the bases of the last two joints 
and on the penultimate one ; palpi above bronzy black. 

Male hypopygium. Lobe of side piece bearing three rods, a 
leaf and a hooked filament, with a tubercle on the lateral aspect 
of the lobe. Qasper curved, concave beneath and with slightly 
winged margins, bearing a moderately long terminal spine. 
Mesosomal plate with the upper arm slender and tooth-like, the 
lower stout, thumb-shaped, seven long slender approximated 
teeth between; horn from the base exceeding the plate, flat- 
tened, twisted, with pointed tip. Tenth sternites tufted with 
spines, the outer spine triangular, but sharp and not dentiform; 
basal arm long, curved, its outer portion embrowned. 

Types, male and female, Bakersfield, California, January 29, 
1924, ‘Timber, between Catch Basin and River’’ (C. K. 
Badger). The specimens are obviously bred, associated with 
Culiseta inornatus Will, and Culiscta maccrackenae D. & K. 

The formation of the lobe of the side piece in the male 
hypopygium in Culex proper consists of three rods, a leaf and 
a seta. The three rods and leaf are in line on the crest of the 
lobe, and the seta is inserted on the lateral aspect of the lobe 
below the leaf. This condition obtains in nigripalpus Theob., 
stenolcpis D. & K., Icpostenis Dyar, chidesteri Dyar and vir- 
pultus Theob., of the species that are before me. The develop- 



ment is in the line of multiplication of the appendages of the 
lobe. The first step is represented by the addition of a small 
filament adjacent to the leaf, its tubercle lying approximate to 
the larger tubercle from which the leaf springs, and lateral 
thereto. Showing this general stage, the following species are 
before me: secutor Theob., salimrius Coq., janitor Theob.,. 
erythrothorax Dyar, bonariensis Brethes ( ?=dolosa Lynch) 
and federalis Dy^r. In erythrothorax and janitor the filament 
is simple and setaform; in salinarius, bonariensis and secutor 
it is hooked at tip and stouter ; in federalis it is strongly hooked, 
and has migrated around the base of the leaf so as to lie beyond 
it, almost coming into line with the rods and leaf. In badgeri, 
here described, the filament is stout and rod-like, though 
strongly hooked, and lies nearly in line with the rods and leaf 
(as in federalis) ; but the seta on the side of the lobe has de- 
generated, leaving only its insertion tubercle to mark its site. 
By simply counting the appendages on the lobe, badgeri would 
fall in the nigripalpus group, whereas by considering the de- 
velopment, it is seen to belong to the salinarius group, and to be 
most nearly related to federalis of Mexico City. 

Since writing the above, further material of this form has 
been received from Major Badger, and the second male 
mounted shows the seta present on the lobe of side piece and 
very strong. This brings the form still closer to federalis, of 
which it may be not more than a race. There still remains the 
difference in shape of the tooth of the mesosomal plate, which 
forms a strong shoulder in federalis, but less in badgeri. 

Aedes melanimon, new species 

In general as in Aedes dorsalis Meig., especially the form 
mediolineata Liidl., exce]>t that the wing-scales are all dark 
or at least unicolorous, there being no contrasting dark and light 
veins as in dorsalis. Nevertheless, I considered this as a variety 
of dorsalis until a male was obtained. The very distinct hy- 
popygium shows that a distinct species is represented. 

Hypopygium. Apical lobe large, nearly bare, a few small 
setae on the inner face; basal lobe of side piece rounded, 
prominent, the inner area bare, the outer sparsely setose: a 



long spine with curled tip and a shorter one, situated on the 
outer aspect of the lobe, the sparse setae following them and 
not more than about six in number except very minute ones. 
Qaspette stem moderate, uniform, the filament longer than it, 
widely expanded and blade-like on the outer two-thirds. Ninth 
tergites small, rather long, with five small setae. Clasper slen- 
der, curved, with a long terminal spine. 

Types, fifteen females, October, 1923, and two males, Feb- 
ruary 26, 1924, Bakersfield, California (C. K. Badger). 


{Dipt era, Culicidae) 

Culex exilis, new species. 

The specimens are much denuded; scales of mesonotum 
coarse, light brown; proboscis, palpi and legs dark, the palpi 
with whitish scales beneath at the bases of the last two joints ; 
head scales more whitish than those of mesonotum; abdomen 
with basal whitish bands, but their extent cannot be made out. 
The colorational characters are indefinite, but the species is 
readily identified by the male hypopygium. 

Lobe of side piece with three rods, two small filaments and 
a large one, a rather narrow leaf and a seta. Gasper curved, 
widened outwardly with expanded margins ; terminal spine 
moderate. Tenth stemites densely spined on the inner side, 
the outer spines forming almost a single row, triangular, not 
tooth-like ; basal arm long and curved, dark brown. First plate 
of mesosome thick, flattened, bent outwardly to project nearly 
at right angles, comparatively short ; second plate with a thumb- 
shaped arm I>elow, the upper angle slender and curving outward 
at right angles ; third plate long, tooth-like, twisted distally and 
lined, ending in a sharp point. 

Types, two males, Vladivostok, Siberia, July, 1923 (T. D. 
A. Cockerell). 

The species belongs to the pipiens group. In Edwards' table 
of the Palaearctic mosquitoes (Bull. Ent. Res., xii, 330, 1921) 



it falls with Theobald ( Theol) accord- 

ing to Edwards, Bull. Ent. Res., xiii, 102, 1922) but this is 
said to be a very small species, whereas the present form is of 
the size of pipiens. The abdominal bands in perexiguus are 
white, while in the present form they seem to be yellowish. I 
have no male specimen of perexiguus, but Edwards states that 
the male hypopygium is as in univitiatus Theob. I have a male 
of this from Lorengo Marques, in which the side piece lobe is 
quite differently shaped, and bears besides the rods, leaf and 
seta only a single long filament, exceeding the leaf. 


{Dipt era, Cuhcidae) 


Some seventy-five years ago mosquitoes were apparently 
commonly received from Chile, and were described by the 
entomologists of the time ; but no material has been received by 
any of the recent workers on the group. Consequently the old 
descriptions remain unidentified and the names cannot be ap- 
plied. The fauna appears to be in large part endemic and 
peculiar, which makes exact knowledge all the more desirable. 

Culex flavipes Macquart. 

Formerly referred to the synonymy of Culex quinqucfascia- 
ius or Culex pipiens; but Doctor Bonne having seen the type, 
pronounces it a small Psorophora or Acdes, (Ins. Ins. Mens., 
xii, 85, 1924.) Concerning the specific characters, nothing can 
be made out from the fragmentary type. Macquart says that 
the scales of thorax and wings are yellow, the legs pale yellow, 
proboscis brownish. The specimen was almost entirely denuded 
of scales at the time of description. 

Culex articularis Philippi. 

Tarsi black, the femora and tibiae with white apices ; thorax 
golden scaled. This suggests a Culex rather than an Aedes^ 
but nothing is given that would determine a positive reference. 



Culex marmoratus Philippi. 

The description suggests a Psorophora. Legs pale grayish 
brown, the hind legs with long vestiture; abdomen marbled, 
and with white lateral spots. 

Culex chilensis Blanchard (varicgatus Blanchard, not 

Legs very pale, almost whitish; wings with scattered black 
spots, the three largest on the costa. Possibly a desert form of 
Psorophora or Aedes. 

Culex serotinus Philippi. 

Theobald (Mon. Culic., ii, 149, 1901) places this as a syn- 
onym of ftavipcs Macq., and redescribes what he takes to be 
flavipcs from specimens of Culex from the Amazon region. 
Theobald s specimens were probably Culex quinquefasciatus 
Say, as he says they are found in large towns and are caught 
with the abdomen full of blood. There is nothing in Philippi’s 
description to negative this reference, and it is quite probable 
that serotinus is a synonym of quinquefasciatus. 

Culex vittatus Philippi. 

Identified by Theobald with Aedes albifasciatus Macquart 
(Mon. Cube., ii, 40, 1901) ; but this species, which is not un- 
common in Argentina, has the mesonotum golden scaled only 
on the sides, the central area being occupied by a paired dark 
brown band and dark brown again on the sides, or as Theobald 
describes it, “reddish brown, with a median yellow line and a 
broader line on each side.” Philippi says: “Tliorax without 
hairs, densely golden scaled.” He described from two females, 
and it does not appear that they were rubbed. The abdomen 
has a median white line as in albifasciatus, but the Chilian form 
is very probably a different species from its Argentinian con- 
gener. The name is preoccupied by Culex vittatus Bigot (1861), 
which is also an Aedes, and consequently I suggest the name 
Aikies philippii for the species. 

Culex annuliferus Blanchard. 

Legs pale, black at the tips of the joints ; abdomen testaceous. 



the segments blackish posteriorly. This also would appear to be 
a desert form of Psorophora or Aides. 

Culex apicinus Philippi. 

Thorax densely golden scaled; abdomen with (basal?) white 
rings ; tips of femora and tibiae and all the tarsal joints (nar- 
rowly?) white. This would seem to represent an Aides. 

Anopheles annuli ventris Blanchard. 

Said by Knab (Am. Journ. Trop. Dis. & Prev. Med., i, 37, 
1913) to be probably a male of Culex or Aides. The legs are 
fuscus, the femora and second and third joints of the tarsi pale 
or whitish ; abdomen dark with basal segmental whitish bands ; 
wings infuscated, darker on the costa. This rather suggests 
Psorophora, which often have the wings infuscated. 

Culex pictipennis Philippi. 

Described from a male, and believed to be an Anopheles. 
Legs cinereus, the tarsi very long, the hind tarsi easily twice 
as long as the tibia, light brown, marked with a black circle in 
the middle, before which is a narrower white ring ; apical part, 
beyond the black ring, all white. 

A small series of mosquitoes from Chile has been in the 
National Museum for years, collected by Carlos E. Porter in 
1912. The following species are represented: 

Culex quinquefasciatus Say. 

Ten specimens, of both sexes, Arica Chinchorra, June, 1912. 

Aides (Stegomyia) aegypti Linnaeus 

Nine specimens, of both sexes, Taital, May, 1912, eight speci- 
mens; Arica Chinchorra, June, 1912, one male. 

Aedes colonarius, new species. 

Female, Proboscis black scaled with slight bronzy reflection ; 
palpi and antennae missing; clypeus black, with white scales 
on either side; tori with small white scales; scales on vertex 
mostly narrow, white on the middle and behind, mixed there 
'with erect black scales, an area of black scales centrally back 



of each eye. Mesonotum blackish, bronzy brown scaled (de- 
nuded centrally) ; a narrow line of white scales laterally, from 
anterior margin to middle of mesonotum; pleura with scat- 
tered white scales ; scales on scutellum and in antescutellar space 
white, the latter mixed with brown ones in front. Abdomen 
black scaled above, the segments with large triangular basal 
white patches, and some white scales on the posterior margins 
of the segments also ; lateral basal triangular white spots, join- 
ing the white scaled venter; a series of large round medio- 
ventral black patches, resting on the posterior borders of the 
segments. Legs black, the femora white beneath, the tibiae 
with a white lateral line; all tarsal joints broadly white ringed 
at base. Wings iridescent, microtrichia present; scales on the 
veins black, appearing coarse and somewhat shaggy, but not 
forming spots; outstanding scales linear, all scales linear on the 
forks of second \ein, Liu on oxhw \eins die ap})re^sed scales 
are ligulate to narrowly ovate. Size rather large, head to end 
of abdomen, 5 mm. 

Type, female, Azapa Valley, Province Tacana, Chile, June, 
19 Vi (C. E. Porter), 


{Diptcra, Cufindci'T) 


Head rounded, the antennae rather small, smooth, with a 
single hair at the middle; frontal hairs, upper single, long, 
lower in three or four, a pair of small multiple (about 10) tufts 
between, antennal tuft multiple (about 6), arranged as in 
triseriatus Say (Howard, Dyar and Knab, Mosq. No. & Cent. 
Am. & W. I., ii, Plate 74, 1918). Lateral aMominal hairs 
double after the third abdominal segment ; short hairs in small 
stellate tufts (4 or 5). Lateral comb of the eighth segment of 
about 8 scales in a single row, the single scale stout with blunt 
tip, not fimbriate. Air-tube blackish, bluntly conical, the pecten 
fine and even, followed by a 3-haired tuft. Anal segment sub- 
triangular, the dark dorsal plate reaching two-thirds down the 



sides. Anal gills large, the upper pair larger and longer than 
the lower pair. Ventral brush short, posterior, with two slight 
tufts preceding it. 

Larvae from a hole in a willow tree, Mission, Texas (R. L. 


(Diptera, Culicidae) 


At my suggestion, Mr. R. L. Turner has been on the outlook 
for this larva in the vicinity of Brownsville, Texas, and has 
now sent in what appears to be the long sought desideratum. 
Specimens were not isolated, but from a mixed culture adult 
thelcter emerged, and of the remaining larvae, the only form 
that cannot be identified with a previously known larva is sup- 
posed to be that of thelcter. The general structure agrees with 
that of the group to which thelcter belongs. 

Head rounded triangular, wider than long, strongly infus- 
cated on posterior border ; antennae small, slender, a small hair 
at the middle. Frontal hairs single. Comb of the eighth seg- 
ment of about 15 scales in a small patch nearly three rows deep 
in the middle; single scale with pointed tip. Air tube short, 
about two-and-a-half times as long as wide ; pecten running far 
out, three-fourths of the tube or more, the terminal teeth 
rather weakly detached. Hair tuft small, but many haired, sit- 
uated about the middle of the tube, well within the end of the 
pecten. Anal segment ringed by the plate, the tuft posterior; 
a dorsal tuft and long hair posteriorly. Lateral abdominal hairs 

In the table (Howard, Dyar & Knab, Mosq. No. & Cent. 
Am. & W. I., iv, 619, 1917), the larva falls with bimactUatus, 
from which it differs in the shorter tube, pecten running further 
out. weaker tuft, pointed instead of feathered and fewer scales 
of the lateral comb and other details. 





In late August of last year R. C. Shannon, J. Zetek, and I. 
Molino paid a brief visit to the little known bat caves of Chili- 
brillo, situated in limestone formation located about a mile from 
the Rio Chilibrillo in Panama. Interesting data on the loca- 
tion and formation of these caves will be found in Proc. U. S. 
Nat. Mus., vol. xlii, p. 21-23, 1912, by Mr. A. Busck. The col- 
lectors have submitted the Orthoptera taken in these caves to 
the writer for determination, and also furnished the list of 
insects of other orders as appended to this report. 

The crickets were collected in the ante-gallery of the caves, 
through which flows a stream with clean, bare dirt banks. The 
crickets were resting on the walls. At the rear of this gallery 
is another chamber with a foot or so of bat guano covering the 
floor. Under rocks resting on this guano covered floor were 
found the various forms of roaches, the largest of which were 
also found resting on the walls of the chamber. Earwigs were 
also collected beneath these stones. 

The orthoptera collected in the caves are considered as of 
sufficient interest to deserve being recorded, though no new 
species are found among their number. The male of a roach 
which was before known only from the female sex is noted and 
parts of the genitalia figured. 

Psalia americana Beauv. 

Three adult male specimens of this earwig were taken, to- 
gether with a single nymph of the same sex. They were col- 
lected beneath rocks on the guano covered floor of the second 
chamber of the cave. 


Xestoblatta immaculata Hebard. 

Two males, two females and a single immature individual of 



this roach were in the collection. The male, up to the present 
time unknown, is very like the female in general structure and 
appearance. The eyes are closer together than in the female,, 
at the narrowest point being barely equal to the greatest width 
of an eye. 

The subgenital plate of the male is somewhat asymmetrical ; 
the left style is a simple organ scarcely longer than broad and 
bearing several hairs, the apical ones fully as long as the style 
itself ; the right style is very different from the left one, being 
an irregularly cylindrical organ about four times as long as 
broad, apically furnished with four sharp chitinous teeth, the 
apical one the stoutest, and basally on the outer side with a very 
long stout spine, over one-half as long as the style itself ; this 
spine is not ordinarily visible as it is normally concealed beneath 
the subgenital plate. Plate IV, fig. A shows the cerci with the 
basal jspine of the right one exposed. The internal genital or- 
gans are well chitinized and api>ear rather characteristic for the 
species; the two main organs arc the right and left genital 
hooks, the right one forming a long sharp simple thorn with a 
swollen and mostly membranous l)ase on which are borne sev- 
eral stout brown bristles ; the left hook rises from a swollen 
membranous base and is itself sub-cylindrical, fully chitinized 
and forms a recurved hook, the apex somewhat twisted, a little 
swollen and fissate, the smaller section forming a sharp com- 
pressed tooth, lying so closely pressed to the larger section as 
to easily escape notice unless examined under mthcr strong 
magnification; this hook is shown in Idatc IV, figure H. The 
above organs normally lie concealed for the greater part among 
surrounding tissue. 

The nymph above recorded shows that the broad huffy 
colored variegation of the tarsi, as described in the original 
characterization and present in paratypic nymphs, is not con- 
stant, being absent in the present specimen. This specimen was, 
however, apjjarently taken when on the verge of shedding, as 
parts of the integument seems to l)e partly separated from the 
underlying portions; this may affect temporarily some of the 
colorational characters. 



Blaberus giganteus Linn. 

Two adult males and several nymphs of this roach were 
taken under rocks in the second chamber of the cave, and also 
on the walls. They were easily picked up and acted as though 
unable to see; they were not frightened by flash-lights and 
even when touched they would not run far. 


Hapithus montanus Sauss. 

A single adult male is referred here with some doubt. The 
species was described from the female sex only and the male 
has never been described. The present specimen is very like 
a rather small and slender specimen of Hapithus agitator. 

Arachnotnimus cavicola Sauss. 

A single male specimen is referred here as it appears to 
agree fairly well with what an adult male of this little known 
insect might be expected to be. The tegmina are represented 
by mere rounded, veinless, scale-like pads. The anterior tibiae 
are without hearing organs, a character of little value, how- 
ever, owing to an extraordinary variation in this respect among 
the genera of the subfamily Oecanthinae. The general color 
of this specimen is dark !)rown, the legs somewhat lighter and 
the antennae with several widely separated bands of a lighter 
color. The femora are very long and slender, the posterior 
ones with a longitudinal whitish stripe on the outer face 
lx)rdered below by black. 

Measurements — Length, pronotum, 2.5 mm. ; anterior femora, 
12 mm. ; posterior femora, 18 mm. ; tegmina, I mm. 

Endacustes sp. 

A single adult male, a smaller and more unicolorously brown 
form than the Peruvian .species described by the present writer 
as £. maculata. It is not thought advisable to describe this 
form as a new species as the systematics of the group to which 
it belongs is now in such an unsatisfactory condition. 




The list of insects here given represents the species collected 
by Zettk, Molino and Shannon. 

In 1913 Mr. August Busck made a collection of insects in 
diese caves. Most of his material is duplicated by mtrs ; how- 
ever he reared a species of Drosophila from the bat guano and 
this is added. 

CoUembola (Determined by J. W Folsom).

It seems remarkable, in view of the careful work that has 
been done in recent years on the venation of Diptera, that the 
significance of the stump vein (labeled in Plate V, Figs. 5 
and 8) leading back from the base of in many of the 
Brachycera has been overlooked. This condition is quite com- 
mon, particularly in the Asilidae and Tabanidae, two families 
exhibiting a comparatively primitive venation. This spur has 
been referred to as a secondary development, but that it is 
part of the atrophied vein Ra seems more probable in view of 
the evidence at hand. 

Commcmly in the Brachycera, the radius is composed of 
Ri, and the radial sector (R^) with three successive branches 
designated by Comstock, and Rr,. This condition 

may be illustrated by the wing of Leptis ( Plate V, Fig. 1 ) 

That the radius is more generalized, however, in certain 
Asilidae, Tabanidae, and Bombyliidae, is apparent when we 
consider that here we have evidence of all four branches of 
the primitive radial sector 

A hypothetical type of primitive Brachycerous wing might 
be illustrated as in Plate V, Fig where all five branches of 
the radius are apparent and as yet no fusion has taken place. 

From a consideration of the radius of a number of forms of 
Asilidae, Bombyliidae and others, treated below, it appears that 
instead of R^ and i?8 uniting, there has been a coalescence of 
Rz and AI4, while i?2 persists as a single vein, or in some cases 
(Mydaidae, Apioceridae, and certain species of Laphriinae and 
Asilinae of Asilidae) unites near the tip with /?i The basal 
part of Rz (that from R2 to the coalescence with /f^), how- 
ever, has atrophied and in most cases is completely lost, al- 
though it still exists as a stump vein in such forms as Brax 
(Asilidae), and Tabanus (scHne), Pangonia (some), and 
Haematopota (Tabanidae), most of the Mydaidae, etc. In the 
Bombyliidae, it persists in a great many cases but has taken 



on the appearance of a cross vein and has been designated as 
an “accessory cross-vein” by Comstock and Needham. 

A very good gradation from a complete Rg with its union 
with /?4 to a complete loss of the basal part of Rg leaving only 
the apparent as a normal fork of the petiole Ri+a is 

found in the family Asilidae. 

In the Asilinae there are several genera {Promachus, M allop- 
kora, Alcimus, Philodicus, and Erax) and in the Laphriinae^ 
one (Pogonosoma) in which Rg is complete, running from R 2 
to (Plate V, Figs. 3 and 4). 

Plate V, Figure 5 is a common type of Erax wing in which 
the basal part of Rg is absent leaving the stump-vein witli 
which R 4 has fused. 

This condition occurs quite frequently throughout the 
Brachycera, being found in the Asilidae, in Erax, Phellus 
Acenphalum, Obelophorus, Laxcnccera (some), Neophoneus, 
Apoclea, Proctacanthus (some); many of the Mydaidae; in 
Haematopota, Pangonia and a few species of Tabanus in the 
Tabanidae; in a few species of Chrysopila (Leptidae) ; and 
occasionally in Thereva (Therevidae). 

In a specimen of Proctacanthus rufus Will, examined, the 
stump vein was quite well developed, although as a rule this 
species has the spur restricted to a minute knob at the angle 
of the vein, or entirely wanting. 

Plate V, figure (> represents the type of venation found in 
the majority of the species of the Asilidae and the rest of the 
Brachycera in which the l>asal part of Rg is completely lost and 
the vein appears to be /? 4 . This condition is found in Erax. 

It may be seen that Erax is included in each set of condi- 
tions and we do find all these gradations in this genus. JS. 
anomalus Bigot and £. candidus Coq. have Rg complete as in 
Figure 3 ; most of them have the distinct angle with the spur 
running basad as in Figure 5; while £. latrunculus Will, ex- 
hibits the condition shown in Figure 6. This difference in 
.venation shows that Erax has strong relationships with both 
Asilus and Promachus, 



A point worthy of note is the fact that in many cases there 
is a distinct angle in the vein at the juncture of R 3+4 although 
the base of Rs is entirely gone, and there is often a minute 
knob at this point as in some Tabanus, Proctacanthus, Coenom- 
yia, etc., showing the derivation of this vein as a product of 
the fusion of the two veins before it has taken over entirely 
the character of a single vein. 

With the Bombyliidae the gradations are also well shown, 
although conditions differ slightly from those in the Asilidae. 
In the former, the branches of the radius have taken more of 
an upward turn, although prolmbly in all cases the union of 
and R4 has been due to the upward migration of R4, as 
this direction of migration seems to be the usual tendency in 
the Brachycera, in fact in all Diptera. In the Bombyliidae the 
numl>er of genera which have present is alx)ut equal to the 
numter which have it atrophied. Some, e.g. Systropus, have 
the radius very similar .to Leptis, etc. ; others, Phthiria, etc., 
have the stump-vein present; while Exoprosopa, Pantarbes, 
etc., show a condition similar to Pogonosoma (Plate V, fig. 4) 
of the Asilidae. Perhaps these similarities tend to show that if 
R^ is present in one group it is present in the others. 

i?8 complete is illustrated by Exoprosopa, Panfarhcs, Eordo- 
ttis. Anthrax, etc. (Fig. 7). 

The spur condition is shown in Phthiria, Bombylius (occa- 
sionally), and Anthrax (Fig. 8). 

The single vein R34-4 is shown in Sparnopolius, Anthrax, 
Bombylius, and Systropus (Fig. 9). 

All gradations are found in Anthrax, as in Erax, In his 
“Dipteres Exotiques,” Vol. II. i)art 1, 1*1. 20 and 21, Macquart 
figures all gradations in this genus. 

In all of these forms there is absolutely no indication shown 
of a fusion of Rs with i? 2 . but on the contrary there is very 
good evidence of a fusion of R^ and R 4 - The foregoing in- 
terpretations eliminate the idea of an accessory cross vein be- 
tween **R 2 A-b' and in the Bombyliidae. They indicate 

further that the Nematocera and Brachycera have a common 
line of descent, instead of different ones as is supposed by 



Comstock in discussing the reduction of the radial sector in 
the wings of Diptera, in “Wings of Insects” (pp. S/)! and 
358), where it is stated: “Not only do we find dilTerences in 
degree of reduction of this vein, but differences in the method 
of reduction are also shown. If the wing of Leptis and of 
Dixa be compared, it will be seen that although in each the 
radial sector is only three-branched, the reduction has Ijeen 
brought about in a different way in the two genera. In 
Leptis, veins R 2 and coalesce; while in Dixa it is veins 
/?4 and /?5 that have grown together. This is a difference in 
kind of specialization, which indicates that the two forms 
(they represent the two suborders, Brachycera and Nemato- 
cera, respectively) “belong to different lines of descent.” 

The new interpretation, however, shows that the Nemato- 
cera and Brachycera are related at least more closely than is 
intimated above. A difference still separating them would he 
the fact that in Dixa R 4 is fused with Rr, but in Leptis Ri is 
fused with Rg. 

In comparing the two suborders, however, a more general- 
ized type of venation should he chosen than Leptis. The sub- 
order Brachycera may be divided into two groups; one grou]), 
in which the costa runs clear around the margin of the wing, 
includes the Bombyliidae, Asilidae, Mydaidae fin some forms 
this is faint on posterior margin), Apioceridae, Therevidac, 
Scenopinidae, Tabanidae and Leptidae; the second, in which 
the costa runs only part way, includes Xylomyia {Suhula), the 
Stratiomyidae, Acanthomcridae, Nemestrinidae, and Cyrtidac. 
The remaining two families not included above, the Empididae 
and Dolochopodidae, should form a group apart from the 
others. Considering the first group at least, it would appear 
that a more generalized type of venation in respect to the 
radius at least, is to be found in the Asilidae and Bombyliidae 
than in the Leptidae in view of the fact that traces of all five 
branches of the primitive radius are present in these families. 




{Dipt era, Tanyderidae) 


The two new species of Tanyderus discussed herein both be- 
long to the subgenus Radinoderus Handlirsch, a division of the 
genus that includes the Chilian Tanyderus gloriosus Alexander 
and the three previously described Australasian species keyed 
below. The subgenus Radinoderus was erected by Handlirsch 
in 1909 (Ann. Naturhist. Hofmus. Wien, 23, 264) to receive 
the single species, ornatissimus f Doleschall). The Australasian 

species of the subgenus may be keyed as follows :

ner division of the lobe of side-piece is darkly colored, while 
the columnar outer division bears a distinct leaf. 


(Dipt era, CuUcidae) 


Several attempts have been made to find this larva, but with- 
out success, until I applied to the original collector, Miss Isabel 
McCracken. She says: 'The larvae sent herewith I gathered 
for class-room work ; but when the first mosquito that emerged 
proved to be maccrackenae I rescued the material for you. I 
found them in a tub of water in which cactus-leaves were be- 
ing macerated. The water in this tub has been undisturbed for 
weeks, and is stagnant and very slimy. Mosquito-collecting 
around the University is becoming difficult owing to the energy 
of the 'Mosquito Abatement Officer.’ ” 

Larva. Head rounded, a little wider than long, the antennae 
short, not exceeding the mouth-brushes. Upper head tuft in 
7 ; lower of two stout hairs and a small one. but the tuft is not 
longer than the upper tuft, shorter rather. The tubercles are 
small ; as in incidens but weaker. Lateral comb of the eighth 
segment of many spines in a patch. Air-tube about three times 
as long as wide, tapered at tip ; pecten teeth elongate and hair- 
like outwardly, even the basal ones being fine and long, with 
two teeth at the base: hairs running out about three-fourths 
of the tube, the distal ones more sparsely spaced. Anal seg- 
ment ringed by the plate, the two anterior detached tufts of the 
ventral brush are in a narrow notch in the chitin, not enclosed 
and puncturing it as in the other Culiseta species. Anal gills 
four, not longer than the segment.

The following items of synonomy, etc., have accumulated in 
the course of work on the Muscoid collections of the National 
Museum : 

Neotrafoia Townsend. 

Neoltafoia Townsend, Proc U S N. M., vol. 4.3, 1912, 313. Type, 
incarum Townsend. 

Charapemyta Townsend, ibid , vol 56, 1919, 589 Type, calida 

Towasend in ]!)ia had only the female, from Cuzco, Peru; 
in mill he included only males, from Rio Charape, Peru. His 
Peruvian material in the National Museum contained three 
additional males from Hruhuasi, Peru. The Museum also 
contains a set of two males and four females, collected by 
Townsend many years ago in the White Mountains of New 
Mexico (South Fork Eagle Creek, August 18 and 21 , and 
North Fork Rio Ruidoso, August 17), which he overlooked 
when describing both genera. This set shows clearly that 
caltda is the male of incarum. There is one sexual difference 
which misled Townsend: the ocellar bristles of the female are 
of remarkable size, erect, divergent and gradually reclinate; 
while in the male they are proclinate and parallel, and not quite 
so large. There is no di.sagreement in the other characters. 

The species was identified by Coquillett as Bxorista kispida 
Van der Wulp, one of the WTiite Mountains specimens still 
bearing his laliel. This I think a misidentification — at least the 
gfenus Neotrafoia is a very distinct one. The species has 




densely hairy eyes ; two large verticals in both sexes ; f rontals 
few and large, the lowest at level of arista; parafacials bare; 
third antennal joint rather wide, especially toward apex; a 
large pteropleural ; scutellum with several erect, tall, straight, 
bristly hairs; no acrostichals immediately in front of the suture. 

Lixophaga Townsend. 

Lixophaga Townsend, Muscoid Flies, 1908, 86 (Smiths. Misc. 
Colls., No. 1803) ; Jour. N. Y. Ent. Soc., xxi, 1913, 303. 
T 5 rpe, Lixophaga parva n. sp. = Hypostena variabitis Coquil- 

Buscnillia Townsend, Jour. N. Y. Ent. Soc., xx, 1912, 111; Ins. 
Ins. Mens., iii, 1915, 121; iv, 1916, 31. Type, Buseniltia 
aurea n. sp. = Hypostena variabitis Coquillett. 

Busemlliopsis Townsend, Ins. Ins. Mens., iv, 1916, 76. Type, 
Busenilliopsis diatraeae n, sp. 

Townsend named the genus Euzenillia from a slide of female 
reproductive organs and eggs, while he was in Peru ; the adult 
from which these came he later searched out in the National’ 
Museum, after he returned, and discovered it to be Coquillett's 
Hypostena variabitis. He associated this female with a male 
of another species, having orbital bristles, when he finally came 
to give the adult characters of Euzenillia (1910, p. 31). 

Coquillett described variabilis from female specimens col- 
lected at Algonquin, Illinois, by Dr. W. A. Nason. While I 
was living at Lafayette, Indiana, I found the species fairly 
common and obtained a series of both sexes. The male has a 
narrow front and no orbitals, just as the type of Lixophaga 
parva, but averages larger than that type. 

PhaeUopsis Towsend. 

Phaenopsis Townsend, Proc. U. S. N. M., 43, 1912, 362. Type, 
arabella new species, from Sullana, Peru. 

DUnasicera Townsend, Jour. N. Y. Ent. Soc,, xxiii, 1915, 62. 
Type, nitida new species, from Sullana, Peru. 

Besides the type specimens there are several others in the 
National Museum from Townsend’s Peruvian material; some 
of them have the abdomen entirely shining, but do not differ 
otherwise. A male specimen from College Station, Texas, sent 



in by Mr. H. J. Reinhard, shows that the species must be 
counted among the North American; it seems strictly typical. 
Townsend's second description is very full and needs no ad- 

Oxynops Townsend. 

Oxynops Townsend, Jour. N. Y. Ent. Soc., xx, 1912, 110. Type, 
scrrattis new species = Hypostena miens Coquillett. Syn- 
onymy by Townsend, Ins. Ins. Mens., iii, 1915, 119. 

Buchaeiaphleps Townsend, Proc. U. S. N. M., vol. 49, 1916, 525. 
Type, Chaetophlcps polita Coquillett. 

This is a case where Coquillett described the same species 
twice. The type of polita has two small hairs on the first vein 
near its tip in one wing, and three in the other; the type of 
nitens has one of the same hairs in one wing, none in the other. 
Thirty -one additional specimens in the National Museum, 
ranging in locality from Lima, Peru, to Mandan, North Dakota, 
with intermediate specimens from Mexico (Yucatan and 
Tabasco), Texas, Florida, etc., show that these hairs are not 
of specific importance. In most they are absent, but in one 
case there are three in one wing and none in the other; and 
in a specimen labeled Oxynops nitens by Townsend himself, 
there are two in one wing, one in the other. Discal bristles 
are generally present, but often weak and sometimes absent 
on third segment. 

Tachixiophyto Townsend. 

Tachinophyto Townsend, Trans. Amer. Ent. Soc., xviii, 1892, 130. 
Type, Tachinophyto ftoridensis new species. 

Pscudomyothyria Townsend, ibid., p. 131. Type, Pseudomyothyria 
indecisa new species. 

Few North American Tachinidae have been more frequently 
misidentified than Tachinophyto ftoridensis. There is a single 
female type in the University of Kansas, and in the National 
Museum there is a male marked type. Both are labeled “S. 
Fla. Robertson." Mr, Robertson writes me that the latter is 
not a type, but that he sent it to Coquillett after the publication 
of the species. It is, however, one of a set of four including 



the type which are all that Mr. Robertson ever obtained. I 
have not seen the other two. I have had the two indicated 
types together and compared them closely, and have no doubt 
that they are the same species. The National Museum has 
two additional females — one from San Rafael, Vera Cruz 
(Townsend), the other from Alajuelo, Panama (Busck). 

Front of male very wide, at vertex 0.34 of the headwidth, 
still wider forward, with two orbitals as in the female; outer 
vertical small but distinct; frontals about 7, the upper two 
reclinate, the second large; lowest at level of tip of second 
antennal joint ; parafrontal and parafacial silvery, the posterior 
orbit also silvery; bucca one-fifth of eye height; second an- 
tennal joint a little elongated, the third long and slender, almost 
three times the second ; arista thickened on basal fourth, penul- 
timate joint short ; vibrissae at oral margin, not approximated, 
four or five good-sized bristles above them, ascending not quite 
to middle of third antennal joint. The face is receding, so 
that the length at antennae compared with that at vibrissae is 
as Ifi to 10. The main characters of thoracic chaetotaxy are: 
presutural 2; supraalar 2, the anterior very large (in the fe- 
male a small third bristle l)efore this); stemopleural 1, 1; 
pteropleural one rather distinct; acrostichal and dorsocentral 
both 2, 3. Abdomen mostly shining, a narrow silver l)order at 
anterior edge of segments 2, 3 and 4, which is very slightly 
interrupted in the middle ; no disrals. The third and fourth 
tergites on the ventral ends have each an oval area of very del- 
icate fine pile in the male, not easily ])erceived but no doubt of 
specific importance. 

In the female the front is narrower than in the male, being 
only 0.24 in the type and 0.31 in the Vera Cruz specimen. The 
difference lies in the wider parafrontals and parafacials of the 

In both sexes the first posterior cell opens almost in the 
apex, and the fourth vein has a rounded bend and is concave 
beyond ; in the female, however, the bend is less oblique and 
the concavity greater than in the male, the apical part of the 



wing being broad and short. The costal spine is strong in 
l>oth sexes, and the third vein has only hairs at base. 

No piercer is present in the female, as 1 ascertained by 
dissection of the Vera Cruz specimen after comparing it with 
the type. Some confusion has arisen on the point, as Town- 
send when he gave the characters in Insecutor Ins. Menst., IV, 
had the wrong female, his specimen l)eing a small 
Doryphorophaga, as shown l)oth by the piercer and by the 
dense group of curved spines on the middle coxa (this charac- 
ter is noted by Aldrich and Webber, Proc. U. S. N. M., 03, 
art. 17, p. 10, footnote). On this page Townsend is comparing 
LAxophaga variabilis and Tachinophyto floridensis, but has the 
wrong male of the former and the wrong female of the latter, 
a very curious circumstance. 

Rumyothyria indccisa Townsend is represented in the Uni- 
versity of Kansas by the single type, a female; it is from 
(arlinville, Illinois (Robertson). I examined it on several 
visits to Kansas (1901, 1914, 1917). I readily matched it with 
s]>ecimens from Lafayette, Indiana, where the species is com- 
mon. The principal difference from floridensis that was 
brought out by Townsend was the presence of discal bristles 
on the second and third abdominal segments. These are smaller 
than the marginals in the ty])e, and in my series are quite 
variable, in several cases being present on one segment and 
absent on the other, or even absent on both. Evidently they 
are not of specific importance. 

The species differs from floridensis in having a small third 
sternopleural, the facial ridges a little more bristly, para- 
facials and parafrontals narrower in the male, costal spine 
absent, pollinose liands of the abdomen broader and more 
diffused, and the fourth vein with a broader, more oblique 
curve, beyond which it is nearly straight. The male has 
orbitals like the female. Besides 27 Lafayette specimens the 
Museum has seven from Attica, Indiana, October 7, 1916; 
and one from Great Falls, X^irginia, August 9, 1923, all col- 
lected by me.

out to a long thin pale yellow fleshy flap. The stemite half 
has near its center two prongs directed upwards, between which 
the usual mid pair of blades show from within. On each side

cross vein. 



Hypopygium. Tergite half ; runs laterally into a fleshy flap 
each side, directed obliquely; in the center between and from 
within, rises perpendicularly a T column like a pile of T's on 
top of one another with the stem pointing into the hypopygium ; 
from the inner base the soft mid pad rises. 

The stemite half, from the middle of its edge have a pair of 
points, the outer side of which angle down low and then up to 
the tip of the lateral corner which appears as a triangular 
point. Prom within are the usual mid pair of blades on each 
side of which are a pair of chitinized spikes, rather longer 
than usual and they have a common base.

pale yellow chitin, with a horse shoe shaped round the anus, 
its arms ending in strong curved claspers directed inwards, in 
front on the inner side of these, rise an upright chitinized 
spike. There are minor things within.

within at the base of this the usual mid pad rises, which is 
spoon shaped. 

The sternite half from near the anus rise a divergent pair 
of chitinized, flat, spiricle appendages. The top lateral corner

superior claspers are about the same but the short chitinized 
pair are bent in the middle and bipronged. 

Described from 3 males and 3 females, Fcrnie, B. C., July 
21 to 24 (C. Garrett). 

Mycomya oviducta, new species. 

Female. A series of six females seem worthy of record. 
They belong to the group possessing pilose epimerum, but 
there are no cerci, and the ovipositor is similar to many found 
in Orthoptera, being slightly chitinized and upturned in a half 
circle, and fully twice as long as the length of the abdominal 
segment. Occiput to front grey-black, face dark, mouth parts 
and bases of palpi dusky, apex of palpi yellow, antennae and 
scape black. Thorax as in Montanus, but the vittae are all 
fused, the whole forming a pattern of a spade in playing cards, 
and polished. Scutellum and pleura dark. Abdomen and ovi- 
positor dark brown. Coxae yellow. Trochanters dusky, all 
claws with a basal tooth. Wing; C does not reach the apex

B. C., September 7 to 24 (C. Garrett). 

Boletina astacus, new species. 

Male and female. Easily recognized by the positions of the 
SC cross veins, which is less than its own length proximad 
of the base RS. 

Occiput to front grey-black. Mouth parts dusky, palpi 
yellow. Antennae, scape, and two or three basal segments of 
the flagellum yellow, the remainder brown. The segments 
hardly twice as long as wide. Thorax, dorsum all polished 



black. In one male, the edges are all grey-primrose; pleura 
dark; coxae yellow, the base of the hind one with a brown 
patch. All claws with a basal tooth. Abdomen brown-black. 
Wing ; C hardly reaches the level of the apex of the wing, and 
is produced past RM nearly one third. Sc joins C just past 
the base of RS ; Sc2 slightly proximad of the latter. The RM 
cross-vein is short, about equal to the basal section of RS. 
Petiole of M very long, nearly equal to Cu2 ; Cu forks a long 
way distad of the RS base. 

Hypopygium. The lateral view is somewhat like a lobster's 
claw. The base of the tergite half is yellow shading to brown, 
and dark brown tips. The whole is narrow, cylindrical, and 
half as long again as any tergite segment. Dorsally from the 
base, it splits in half, the apical third being thumb-like. Stem- 
ite half is dark brown and runs the full length, ending in an 
oval tip. There is an open space between the tergite and 
stemite tips for the apical third as they do not occupy the full 
depth of the s^^ent. 

Descril)ed from 2 males and 1 female, June 16, Caulfields, 
B. C. (R. S. Sherman). 

Boletina anticus, new species. 

Belonging to the gracilis group. Male. Occiput to face 
grey-black, palpi yellow; Antennae long and thin; Scape yel- 
low-brown, flagellum black brown, the segments long and nar- 
row, perhaps four times as long as wide. Thorax; dorsum 
brown with three distinct black vittae, scutellum brown. All 
hairs and bristles yellow. Pleura brown to dark ; a row of 
short yellow hairs along the hind mesopleural suture. Coxae 
yellow, the hind one dull, all claws with a basal tooth. 
Halteres yellow, the tip dusky. Abdomen dark brown, the ex- 
treme posterior edges showing some yellow; Wing; C and 
RS nearly reach the apex of the wing, and C is very slightly 
produced ; Sc joins C proximad of RS ; Sc2 is about the mid 
of the former. Petiole of M about 1J4 or 2 times as long as 
the RM cross-vein and longer than Cu2 ; Cu forks far past RS 
and near to the fork of M. 



Hypopygium ; somewhat the shape of Johannsen^s fig. 168, 
but is deeper, forming more of a triangle. Compare fig. 162 ; 
in this species the dorsal plate is divided into three parts. The 
central part has a straight end on which are a pair of cerci 
like appendages. The inner corner of the side piece of the 
dorsal plate runs up into a triangular point, the tip reaching 
half way up the cerci-like appendages. The lateral superior 
claspers are straight, the tip is capped by a bunch of short 
thick black hairs ; near the tip on the inner side is a notch and 
a small cylindrical appendage from it. The stemite half has 
a split base, which about half way angles out, forming a square 
frame round the penal appendages; here is a pair of strong 
hooks and a stem but no basal hood. 

The female has distinct pale yellow posterior margins to the

Boletina antomus, new species. 

Male. Very similar to Boletina anticus except, scape more 
yellow. The two hind coxae have apical dusky patches or 
wholly so. Tip of the halterers yellow. Hypopygium as 
B. anticus, but the dorsal cerci-like appendages are different, 
being narrow. The inner corner of the side piece in the dorsal 
plate ends in a fine small point which runs into a long triangular 

The stemite half is similar to B. anticus, but lacks the mid 
pair of hooks, having instead a cucullus over the penal ap- 
pendages. The inner side of the superior claspers both in 
anticus and atomus is set with many short chitinized tubercles.

Boletina shermani, new species. 

Belongs to the nacta group. In the type description of 
nacta Johnn., the hypopygium is said toi be as Boletina graciUs. 

INSECUTOR INSCm^ menstruus 


This spedes has the general shape of fig. 150 given for 
imitator, and also lacks the smaller bi-pronged basal claspers. 
If I have judged wrongly, then I have another species of the 
antenus group, which I now call ''gracilis'' Johnn. 

Male. Occiput to face grey-black, palpi yellow. Antennae 
brown-black. Thorax, dorsum dull brown, with three indis- 
tinct vittae of a darker shade. Pleura grey-black. Coxae yel-

petiole of M about equal in length. M forks l)e!ow base of 
RS, Cu forks slightly proximad. Hypopygium, all black ex- 
cept the long pair of sternite claspers, which are pale yellow, 
each has a long bristle on the inner side above half way, and 
a shorter one above, and bi-pronged tips. The mid piece below 
also runs nearly to the apex of the tergite half. The dorsal or 
ventral view of the whole is pear-shaped, the apex being about 
half the width of the base. 

Described from 3 males and 7 females from Vancouver, 
Capilano, and Seymore Creek, all in British Columbia, April 
and May (R. S. Sherman). 

Boletina jucunda, new species. 

Male; Occiput to front grey-black. Face and mouth parts 
dark to brown. Palpi yellow or dusky ; Antennae dark brown 
Thorax grey-primrose, the three vittae slightly showing, 
smooth ; scutellum dark. All hairs and bristles yellow. Pleura 
grey-black. Coxae yellow, the two hind ones blackish. All 
claws very small and modified, scoop-shaped. Abdomen and 
hypopygium dark brown. Wing; C reaches the apex of the 
wing and is produced half way past RS ; Sc joins C over the 
base of RS ; Sc2 is far distad of mid SC ; RM cross-vein is 
shorter than the petiole of M ; Cu forks slightly distad of the 
proximal end of the RM cross-vein. Hypopygium: General 
shape as fig, 146 given for obscura, but the lateral flaps have 
no chitinized hook, but have two inner points, the lower one 



with a small nail-like claw on it. The pair of curved claspers 
shown in between these are long, reaching the apex of the 
hypopygium and are divergent. There are other minor points 
of difference. 

The type series is from British Columbia but I have not 
the full notes with me. 

Boletina differens» new species. 

Allied to the noc/a group and shermani, the position of the 
fork of Cu is apt to throw it to genus Phthina, but I would 
consider it a true Boletina, 

Male. Occiput to front grey-black; face and mouth parts 
dark brown ; palpi yellow. Antennae, scape dark brown, 
flagellum black. Thorax; dorsum grey-brown, opaque, with 
three smooth black vittae. Bristles and hairs yellow-brown 
Pleura grey-black, propleura brown. Abdomen black-brown. 
Hypopygium yellow-brown, the apical half of the tergite 
black. Coxae yellow, trochanters slightly blackish. Claws of 
the fore legs missing, but those of the hind legs apparently 
simple, but they might have a small basal tooth hidden by the 
pulvi. Halterers yellow, tip slightly dusky. Wing ; C does not 
reach the apex of the wing, and is not produced past RS; 
Sc enters C proximad of RS and about over the middle of the 
RM cross-vein, which is straight or nearly so, appearing like 
a longitudinal vein, and the petiole of M hardly twice as long 
as the latter ; Cu forks below or slightly distad of the fork of 
M ; Sc2 is about mid SC. 

Hypopygium somewhat similar to B, shermani, but the long 
pale yellow claspers have only one tip.

Boletina unusus, new species. 

The position of the forks Cu would tend to place it in genus 
Phthina but 1 would consider it a true Boletina, 

Male; Occiput to front grey-Wack, face and mouth parts 
brown, palpi more yellow. Antennae: scape and next two 
joints yellow, the next six blackish, and hardly longer than 



broad. The remainder brown. Thorax is yellow-brown, the 
three vittae fused and occupying most of the dorsum; scutel- 
lum brown; pleura and metanotum yellow, the latter with a 
dark central patch. Abdomen; tergites mixed, no definite 
sharp pattern, but the segments appear to have bases dark 
brown witli their centers produced nearly or reaching the 
posterior margins, the lateral parts and apical corners yellow 
to brown. Coxae yellow, trochanters blackish, of the five legs 
present, there are only claws on the fore leg. These are very 
small and modified. Haltres yellow. Wing ; tips are damaged. 
SC enters C over RS ; Sc2 is distad of SC. The RM cross- 
vein and petiole of M about equal ; Cu forks distad of the M 
fork. Hypopygium is shafted l)etween fig. H() and fig. Ie50, 
being those of obscura and imitator The forceps are also a 
grade l)etween, the outer or fleshy part of the claspers are 
elongate but not as long as in fig. 150, the basal chitinized spine 
is quite short and curved, its tip ends in two points. Between 
these appear what may be the usual blades and ix)ints com- 
monly found in Mycomya

(Diptera, CtUicidac) 


Anopheles vestitipcnnis D. & K is known only from the fe- 
male adult, with peculiar distribution, Mexico, Guatemala and 
the Greater Antilles (Cuba and Jamaica). It has not been 
taken in Costa Rica or Panama. 

Last summer, Dr. W. C. Earle, of the International Health 
Board, Rockefeller Foundation, bred the species in Porto Rico, 
adults in June. The larvae sent are immature, but the male 
hypopygium is worthy of description. 

Using the terminology of Dr. Root’s paper (Amer. Journ. 
Hygiene, iii, 264-279, 1923) for the sake of comparison, the 
species falls in the subgenus Anopheles, having two basal 

Side piece twice as long as wide, strongly chitinized, with an 
apical slit to receive the clasper when bent; many scales on 
the outer side. 

Basal spines two, arising separately, without prominence or 
common chitinization, nearly equal and curved at tip. Internal 
spine slender, moderately long, curved and with tapered tip. 

Clasper half again longer than the side piece, strongly chiti- 
nized, with two very minute setae before tip. Apical claw stout, 
very short. 

Claspette; ventral lobe strong and well chitinized, prominent, 
with two spines, one of which is enlarged — spatulate at the tip 
and encloses or is fused with the other. Dorsal lobe setose with 
two spines at tip, the outer one stouter than the inner. 

Mesosome moderate, with a single long stout smooth spine 
on each side at tip. 

Processes of the ninth tergite strongly developed from conical 
bases, stout, tips conical, as long as the fused spines on dorsal 
lobe of claspette. Anal lobe prominent, setose. 

Nearest to grabhamii Theobald, differing principally in the 
less chitinized and produced base of the basal spines, and in the 
more strongly developed processes of the ninth tergite.

Aedes alopotiotum Dyar. 

/Icdes aloponotum Dyar, Ins. Ins. Mens., v, 9S, 1917, 

Aedes fletcheri aloponotum Dyar, Ins. Ins. Mens., viii, 112, 1920. 
Aedes flavesccns (?) aloponotum Dyar, Proc. U. S. Nat. Mus., 
Ixii, 75, 3922. 

Aedes riparius (?) aloponotum Dyar, Ins. Ins. Mens., xi, 92, 1923. 

This species, hitherto known only by females, bears a strik- 
ing resemblance to Aedes riparius, which I at one time confused 
with flavcscens Miill. {fletcheri Coq,). Except for the detached 



distribution, I would probably have referred it to the synonymy. 
In order to settle the question, a special trip was made to the 
Puget Sound region in the spring of 1924. A pond was found 
near Hoodsport, Washington, heavily overgrown with a water- 
plant, which Mr. Paul C. Standley has kindly determined as 
Veronica scutellafa. The water was very cold, and no larvae 
were visible; but by persistent dipping with a strainer, a con- 
siderable number were obtained. By the larva and male hy- 
popygium it is seen that the species is not related to riparius, 
but comes very close to evcrucians Walk. There are slight 
differences, however, and I cons>ider that a distinct species is 

Male hypopygium. Side piece three times as long as wide, 
the tip rounded, hairy, with a few small scales on the outer 
side ; apical lobe conical, prominent, with many small delicate 
setae from rather large tubercles ; no basal lobe, the rugose area 
running up to base of apical lobe. Claspette stem rather long, 
slender, markedly con.stricted at apical fourth, the tip a little 
expanded at insertion of filament; filament shorter than the 
stem, with widely expanded blade, sharply cut at base and 
tapering to tip. Ninth tergites small, with five spines, three 
times as long as the prominence. 

Larva. Antennae slender, rather long, infuscated outwardly, 
spinose, a 6-haired tuft near the middle. Clypeal hairs coarse, 
upper in 3 or lower in 2. Lateral abdominal hairs single 
'diU'v the second segment. Skin minutely spicular, quite strongly 
and densely so. Scales of the comb of eighth segment about 
35, in a patch three rows deep, the single scale with distinct 
central spine, stronger than the lateral spines. Air tube nearly 
four times as long as wide, regularly tapering outwardly, with 
long terminal hooks ; pecten of about 25 teeth, the last or last 
two teeth detached, rarely not any detached, followed by a large 
six-haired tuft. Anal segment longer than wide, the dorsal 
plate reaching near the ventral line but not encircling; ventral 
brush with small tufts preceding ; dorsal posterior hairs a single 
hair and large tuft on each side; anal gills four, equal, longer 
than the segment. 



The adults appeared during May. The habitat of this form 
is remarkably restricted. It occurs so far as known only in 
the Puget Sound region southward to Mount Rainier. Specific 
localities are: 

Nanaimo, British Columbia (Vancouver Island), August 
6, 1906 (Dyar & Caudell). 

Mission, British Columbia (Fraser Valley), July 14, 1919 
(E. Hearle). 

Harrison, British Columbia, June 20, 1919 (E. Hearle). 

Agassiz, British Columbia, May 23, 1919 (E. Hearle).

(H. G. Dyar). 

Hoodsport, Washington, July 7, 1920 (H. G. Dyar). 

Ashford, Washington (Mount Rainier region), August 1, 
1906 (Dyar & Caudell). 

Aedes fitchii palustris Dyar. 

This species was bred from the same pools that produced 
aloponotum, the palustris emerging first. The form accom- 
panies aloponotum throughout its distribution, but exceeds it 
considerably, ocairring southward along the mountains to cen- 
tral California, and northward in favorable locations to Alaska. 

ASdes aboriginis Dyar. 

This species breeds in early snow pools and also, rarely, in 
dark pools in deep forest, in which location the emergence is 
much retarded. These larvae in the dark forest pools are much 
preyed upon by Eucorethra larvae, which those in the open 
pools escape. In some shaded ditch-pools near Bremerton, 
Washington, belated larvae of aboriginis were taken singly at 
the end of April, 1924. 

The distribution of this species is coincident with that of 
aloponotum in its southern extension; but it extends further 
to the north. It occurs at the foot of Mount Baker and along 
the coastal region of British Columbia and Alaska, as far as 
the barrier islands extend, except at the river mouths, where 
the Canadian fauna pierces through to the coast. 



Alkies cinereus Meigen. 

This little species pays little attention to the boundaries of 
faunal regions, but occurs generally throughout forested 
country. It invades the lower portions of the Pacific coastal 
area, being found rarely in the Puget Sound region. Larvae 
were found in the edges of a large lake, half a mile across, 
near Hoodsport, Washington. In spite of its size, this lake 
goes completely dry in the summer, and so has the character of 
a temporary pool. 

The Culex and Culiseta of the region are not so peculiar in 
their distribution, and have been adequately commented upon 



(l)ipiera, CuHcidar) 


In the monograph ( Howard, Dyar & Knab, Mosq. No. & 
Cent, Am. & W. I., iv, 729, 1917), we treated the American 
form of this species as Addes fuscus O. S., but called attention 
in a footnote to its identity with the European Aedcs cinereus 
Meigen. This synonymy has been followed since; but never- 
theless, the two forms are not identical. In the European 
specimens examined by me, at least in the females, the broad 
scales on the head practically meet vertically, whereas in the 
American form there is a very distinct channel of narrow scales 
reaching through to the vertex. The American form, therefore, 
may he called Acdes cinereus fuscus O. S. 

The subspecies has a wide distribution in Canada and 
America, following in the main wooded country, although not 
reaching to high altitudes or very far north. With this wide 
distribution, it is never locally abundant. In California, how- 
ever, a modification occurs. At about the 7,000 foot level, the 
species takes on a change in coloration and habits, for which 
I propose the name 

Aedcs cinereus hemiteleus, new race. 

The channel of narrow scales on the vertex of head is wider 



than in cinereus fuscus; the mesonotum is bronzy brown, with 
two longitudinal black lines and posterior short side stripes; 
the abdominal bands are variable, often well developed, the 
lateral widenings touching, but not forming an even lateral 
band; venter frequently with a more or less distinct median 
dark band. 

Types, five females, Lakes Center Camp, Plumas County, 
California, June 30-July 1, 1920 (H. G. Dyar). The form 
was also found in numbers in the valley of the Merced River 
above 7,000 feet, at Lake Merced and Lake Washburn in June, 
1924. The season this year was remarkably early, and adults 
were on the wing and somewhat worn. Complaint was made 
by the caretakers at Lake Merced that “a .small black mosquito*' 
had been biting about a week before our arrival, which would 
have been during the last days of May. On June 8 they were 
no longer biting, but had returned to the meadow, where fed 
females could easily be flushed from the grass. Males were 
present in the meadow, all under a single willow bush, which 
presented no apparent difference from any other willow, yet 
here were three or four hundred males under this brush and 
none elsewhere. The females also were in the same vicinity. 

The Merced River flows through a solid, glacier-worn, rock 
bed, and where this bed rises, lakes are necessarily formed. 
Both Merced and Washburn Lakes are of this character. At 
the upper end of each lake, the incoming silt has formed a 
meadow, and the waves beating back against this, have thrown 
up an elevated beach. Behind this barrier in the low meadow, 
pools are formed bv high water. The peculiar nature of the 
local breeding places, the large number of specimens occurring 
where found, the exodus to feed and the marked return home 
of fed females, all indicate a departure in habits from those of 
cincrcus fuscus. 

Eggs were obtained from females taken from the meadow, 
single egg long, fusiform, about five times as long as wide, 
flattened on one side, shining black. 

It is evident that the male which I assigned to Aedes veniro- 
vitlis fins. Ins. Mens., viii, 172, 1920) is this species.

Aides (Aedes) ventrotnitis Dyar, Proc. U. S. Nat. Mus., Ivi, 94, 

The larva of ventrovittis lieing supposedly unknown in the 
spring of 1921, I took advantage of information furnished by 
Professor Stanley B. Freeborn that a large breeding meadow 
of the species existed at the head of Fletcher Creek in the 
Vosemite National Park, at an elevation of 9,000 feet. After 
making the trip from Yosemite Valley to Merced Lake to 
which I was most kindly assisted by Mr. W. B. Lewis, Super- 
intendent of Yosemite Park, we found yet a long trail to the 
summit. Merced Lake is at an altitude of 7,200 feet, the re- 
maining 2,000 feet being a steep climb. We undertook this; 
but when several miles below the summit, ventrovittis females 
appeared and eager to bite. A male was secured, at about 8,000 
feet, feeding on the catkins of a small willow bush, which to 
my surprise, proved to be a male of fisheri Once given this 
hint, a comparison of the types of fisheri and ventrovittis es- 
tablish'^d the above synonymy. The color of the mesonotum 
varies considerably, from brown to light gray, through a green- 
ish gray ; there may be fairly distinct brown lines or none. 

The larva has been described by me (as fisheri). The species 
breeds by preference at high altitudes, where the pools are 
kept filled by direct drainage from melting snow. In the 
Fletcher Creek locality. Professor Freeborn encountered the 



adults in thousands. Lower down the breeding is less abundant. 
At Summit, Placer County, California, 7,000 feet, solitary larvae 
were found in little pools in a meadow through which snow- 
water was running. At Lake Tahoe, 6,000 feet, I found a 
ditch-pool beside a road into which water was running from a 
melting snowbank on the other side of the road. This pool 
was dry the next day, and obviously no adults could have 
emerged. Larvae were brought home to rear; but on adding 
fresh water to the culture, they all died, the necks extended 
and the intestines protruding from the anal opening. I trans- 
ferred them as quickly as possible to their own water, but all 
died. I have never seen larvae as sensitive to osmosis as these 
were. The difference between the waters must have been 
slight. The original pool was filled by melting snow, probably 
condensed somewhat by evaporation, but perfectly clear. The 
water at the house was taken from the piped water from a 
stream supplied by melting snow. In carrying cultures from 
the collecting ground, it is usual to carry as little water as 
possible, and then fill up the cultures at home. I have done 
this hundreds of times without any ill effect; this time it was 

Eggs were obtained from captive females at Merced Lake. 
Fusiform, about three times as long as wide, flat on one side; 
shining black. Laid singly. The females oviposited in about 
five days from time of capture, which is an unusually short 
period ; four weeks is not uncommon as an incubation period. 

The adults emerging at the head of Fletcher Creek migrated 
down from the summit on all sides, to a distance of ten miles 
or more. Then, after biting, they obviously returned, as the 
species does not breed at Merced I^e, nor probably on the 
Tuolumne Meadows on the other side. Breeding is very local 
in this region, as most of the country is composed of bare 
granite ledges and dry forest. It is therefore quite easy to 
observe the habits of the species of mosquitoes present.

(Diptera, Culicidae) 


In this journal, Vol. xii, pp. 119-124, 1924, 1 mentioned some 
new mosquitoes from Colombia collected by Major L. H. Dunn. 
A badly placed mount deceived me in describing sursumptor 
(page 123) ; the structure is really the same as in ligator, which 
is correctly described. The following is the synonymy : 

Culex (Choeroporpa) sursiunptor Dyar. 

Culex {Choeroporpa) sursumptor Dyar, Ins. Ins. Mens., xii, 123, 

Culex {Choeroporpa) Uyator Dyar, Ins. Ins. Mens., xii, 123, 1924. 
The species falls in the place of inhibitator D. & K. in the 
tabic (Ins, Ins. Mens., viii, 81, 1920). Inhibitator itself is 
wrongly placed, owing to a poor slide. A leaf-like appendage 
is really present on the outer lobe of the side piece and the 
species should be placed with leprincei, from which it differs 
in certain details. 

Major Dunn has recently sent further collections, of which 
one is of special interest. The specimens were caught on board 
the river steamer, “Quibdo,"’ while tied to the bank at Murindo 
on the Atrato River, between 8 and 10 p. m. Many males of 
the small species of Culex came to the boat, of which the follow- 
ing are noted: 

Culex (Microculex) imitator Theobald. 

Indicating the presence of epiphytic Bromeliaceae near the 

Culex (Aedinus) amazonensis Lutz. 

This little species seems to favor the shores of rivers, but its 
habits have not been made known. The distribution is wide. 

Culex (Melanoconion) dunni Dyar. 

We found this species in Panama breeding in the grass 
along the edge of Gatun Lake. The distribution is now ex- 
tended, and the species probably reaches Surinam (.see Ins. Ins. 
Mens., xi, 188, 1923). 



Culex (Choeroporpa) eastor Dyar. 

This little species, described from the coastal region of 
Surinam, appeared in considerable numbers, 26 specimens being 
obtained. This both extends the known distribution and gratify- 
ingly augments the material in the collection. 

Culex (Choeroporpa) crybda, new species. 

Male antennae comparatively short, the end of the penul- 
timate joint not quite reaching tip of proboscis, the last two 
joints slender, sparsely setose; black, a small whitish mark at 
base of penultimate joint and middle of long joint. Occiput 
black scaled, with many erect forked ones, a small white patch 
on the side next the eye. Mesonotum dark brown. Abdomen 
black, with basal segmental white bands which are very nar- 
row centrally. Tarsi dark. Wing scales ovate on the forks 
of the second vein. 

Hypopygium. As in epanastasis Dyar; the tenth sternites 
have six instead of ten teeth, and the mesosome is very differ- 
ent, being long, smooth and horn-shaped, with but a single 
terminal point ; a long thorn-like branch at the middle at right 

Type, one male. 

Culex (Mochlostyrax) coloipbiensis, new species. 

Antennae exceeding the proboscis by the length of the last 
two joints, which are slender and setose, black. Occiput entirely 
with flat white scales and small sparse erect forked black ones. 
Mesonotum brown. Abdomen black above, without bands, dark 
below. Tarsi dark. Wing scales ligulate on the forks of second 

Hypopygium. As in hesitator D. & K. ; the mesosomal plate 
has a remarkable double hook at the tip of the apical point on 
the side where there are two points, wholly lacking in hesitator. 

Type, one male. 

The separation of the spedes of Mochlostyrax can now be 
improved over that formerly given by me (Ins. Ins. Mens., vi, 
107, 1918).

I have no authentic male of this species, the cot>T)e left by 
Dr. Bonne being a female. However, one of the specimens under 
alogistus differs, and I am supposing this to be multispinosus. 
It seems unlikely that there are more than two Mochlostyrax in 
Surinam. The original desciiption must be in error in de- 
scribing lateral lobes and also small normal basal ones. Some 
other structure, I think, has been mistaken for nearly hairless 
aborted ninth tergites, while the true ninth tergites are well 
developed as in caudelli and alogistus.

I have this widely spread species frcxn the Antilles, Florida, 
the Gulf States, Mexico, Costa Rica, Panama, Ecuador and 
Surinam. As shown by Mr. W. H. W. Komp (Ins. Ihs. Mens., 
xi, 133, 1923), the larvae live in temporary rain-pools, not in 
permanent water as is usual with Culex. Mr. Shannon and the 
writer found the larvae abundant in surface water following 
rain in the jungle near Gatun, Canal Zone, associated with 
Psorophora cilipes Fab., Psorophora posticatus Wied., Aedes 
serratus Theobald and Aedes hastatus Dyar. The larvae fasten 
themselves by the air-tubes to objects on the bottom of the 
puddle, and when in a glass jar are seen boring vigorously in 
an attempt to fasten themselves.

We wished to dedicate this species to Mr. Turner, on account 
of his intelligent interest and indefatigable collecting in the 
lower Rio Grande Valley; but he urged us to name it after 
Mr. R, E. Tarbett, his chief in the Public Health Service, whose 
liberal policy in encouraging the inspectors to become acquainted 
with the species of mosquitoes in addition to routine extermina- 
tion work gave Mr. Turner the opportunity to make this dis- 
covery. The embarrassment of choice thus forced on us has 
induced us to give the insect a non-committal name.

{Lepidoptera, Thyrididae) 


Six species of Thyrididae are known in the United States, 
contained in five genera. Of these, Hexeris, Meskea and 
Thyridopyralis arc gall-makers as larvae, Dysodia lives in rolled 
leaves, while the larvae of Thyris arc unknown. The European 



Thyris are said to live in rolled leaves (See Hofmann, “Die 
Raupen der Gross-Schmetterlinge Europas,” 34, 1893). I am 
now able to confirm this for one American species. 

Thyris maculata Harris. 

The larva lives on Clematis, and may be found fully grown 
in August. The case is made by cutting a slit parallel to the 
margin of the leaf, near the margin for young larvae, near the 
center of the leaf for large ones. The larva rolls the leaf as it 
cuts and spins it fast by the inner margin so that a spreading 
roll is formed, open below. The larva rests in the top part 
of this retreat. 

The larva is thick and stout, light orange color, with large 
round black tubercles, iv, and v setae on one tubercle. Head 
orange-red, the mouth parts scarcely darker. Cervical shield 
large, orange, with a black patch on each side and at the lower 
edge. Thoracic feet and anal plate black. 

Larvae from Washington, D. C., on a clematis vine in my 
hack yard.

piece. Ninth tergites slender, finger-shaped, rather long, from 
broader conical base. 

This may be Dixa fusca Loew; but without a more minute 
examination of specimens from the type locality than has been 



possible to us, we are unable at present to decide the point. 
Dixa fusca was described from New York. 

Types, six males, No. 27452, U. S. Nat. Mus. ; Dead Run,

Dixella is proposed. 

Type, male, No. 27455, U. S. Nat. Mus. ; Monte Lirio,

The genus Dixa may be subdivided into the following sub- 
genera; besides Dixella above mentioned, marginata Loew 
seems also separable on the characters indicated below, and for 
this we propose the subgeneric name Dixapuella.

(Dipt era, CuHcidae) 


The interest which followed the discovery of the role of 
mosquitoes in the transmission of disease, and which resulted 
in their intensive study after the year 1900, did not affect the 
present subfamily of non-biting Culicidae. Very little attention 
has been paid to the American non-biting forms, the Chao- 
borinae and Dixinae. We consider that these three groups 
belong to a single family on account of the peculiar venation 
which is common i.o them all and does not exist elsewhere in 
the Diptera. The differences between these subfamilies appear 
in tabular form as follows : 



Subfamilies of Culicidae 

Al. Eyes reniform; flagellum 13-jointed; proboscis extending 
far beyond clypeus ; mesostemum ridged ; lateral sclente 
of metasternum triangular, in line with (Megarhinini, 
Sabethini) Or below (Uranotaenini, Anophelini, Culicini) 
the base of hind coxa; wings scaled, hind margin with 
fringe of scales; forking far before tip of Sc; upper 

squama bare or ciliated Culicinae. 

A2. Eyes more or less emarginated on mesal line; flagellum 13- 
jointed; proboscis extending but little beyond clypeus; 
mesostemum without ridge; lateral sclerite of meta- 
stemum much reduced, not triangular ; wings with hair- 
like scales, hind margin with fringe of scales; forking 
far before tip of Sc ; upper squama ciliated . Chaoborinae^ 
A3. Eyes not emarginated, nearly circular in outline; flagellum 
14- jointed; proboscis not extending beyond clypeus; 
mesostemum without ridge; lateral sclerite of meta* 
sternum much reduced, not triangular ; wings with only 
inconspicuous hairs on veins, hind margin with fringe 
of sparse hairs; R„ forking approximately opposite tip 

of Sc; upper squama bare Dixinae, 

The species of Chaoborinae in North America are com- 
paratively few. Two, and perhaps more, are also found in 
northern Europe, and the distribution of the species is in gen- 
eral wide. The immature stages are aquatic, in the larval stage 
predaceous. The species are of little economic importance, for 
although all the species are predaceous as larvae, and will eat 
mosquito larvae, still their diet is not confined to these, and 
many species, especially those occurring in abundance, frequent 
large ponds and lakes where no mosquito larvae occur. Prof. 
C. Juday has found the larvae of Chaoborus (Corethra) in 
lake water at a depth of fifteen meters where anaerobic condi- 
tions prevail. 

The material in the National Museum was fortunately supple- 
mented by ttet of Dr. J. M. Aldrich. His collection contained 
autl^entic specimens of several of the species described by Dr. 
p:. P. Felt. Mr. C. W. Johnson has kindly given us a specimen 
^ of his Chaoborus albatus. 



In general characters the Chaoborinae are: 

Very small to rather large, pale to dark species, with or with- 
out markings ; with hair-like scales on wings and fringe on hind 
margin of wing. 

Eyes more or less reniform ; antennae fifteen- jointed (flagel- 
lum thirteen- jointed) ; palpi five-jointed; proboscis very short; 
clypeus usually long and densely setose ; pronotal setae few and 
usually near upper margin; prealar, mid and lower sterno- 
pleural setae present, rarely absent. 

Type genus of subfamily, Chaohorus Lichenstein (Wiede- 
mann's Arch. ZooL, I, 174, 1800). 

The type of Corethra is Tipula culiciformis De Geer, being 
the only species included by Meigen in proposing the name 
Corethra, Edwards (Ent. Mo. Mag., Ivi, 265, 1920), however, 
says : “Coquillett, and those who follow him, overlook one all- 
important fact. In his later work Meigen indicates that he did 
not know T. culiciformis, and therefore we must assume that 
at the time he first described Corethra he had another species 
under De Cker's name. No doubt this insect was the one he 
later described as C. lateralis, which is a synonym or variety of 
C. crystallinus,** 

It appears to us that these assumptions are unnecessary. 
M eigen's description is obviously based upon De Geer's figure, 
since, as he admits, he did not have specimens of the species. 
His description is as follows: 

“Corethra. Die Fuhlhorner vorgestreckt, vierzehenngliede- 
rig ; bei dem Mannchen biischelf ormig behaart ; bei dem Weib- 
chen borstig. Die Fliigel flach parallel, haarig." 

So good an entomologist as Meigen would not have adduced 
as a generic character “wings flat, parallel" from an actual 
specimen. That is the appearance given in De Geer's figure, 
but is an attitude seldom assumed in a cabinet specimen. Four- 
teen joints to the antennae is the number shown in De Geer's 
figure, who, however, describes and figures only the male. 
Meigen's addition of “bristle-shaped in the female" for the 
antennae may have been adduced from the general rule In the 
family. The peculiar short joint in the tarsi is not shown in 



De Geer’s figure, the joints being indefinitely drawn^ to as many 
as eight. 

In the “Syst. Beschr. Europaischen zweifl. Ins,” Meigen uses 
Corethra for crystallina and pallida, including adiciformis as 
unknown to him ; but this has no bearing on the original desig- 
nation of type.

Eucorethra underwoodi Coquillett, Canad. Ent., p. 273, 1903. 

This genus contains only one species which is of widespread 
northern distribution. The larvae are predaceous with short 
air-tube, lying flat near the surface of the water, and are found 
in cold springs or small pools of clear water usually in deep 
woods, sometimes in rain water barrels, not in open sunlit 



pools. They are very destructive to mosquito larvae. In the 
spring, they are often abundantly supplied with food by the 
larvae of the early emerging Addes. Later larvae must wait 
the chance oviposition by CuHseta. The senior author has often 
observed belated Eucorethra larvae thus patiently waiting in 
otherwise empty woods-pools. Qasp of male genitalia with 
claw; tenth sternites shaped as in Corethra ctUiciformis, but 
pale and incon^icuous.

Corethra cinctipes obscura new variety. 

A series of males and females of this form were reared from 
a large lake which goes dry in summer, at Hoodsport, Wash- 
ington, May 2-8, 1924 (H. G. Dyar). The larvae occurred 
among logs in shallow water near one end of the lake, asso- 
ciated with Aedes cinereus Meigen. The adult differs from 
the eastern United States form by being of an uniformly smaller 
size and general darker color.

Corethra, Auctorum. 

Small to fairly large sized species, with or without markings 
on wings or legs. Basitarsal joint longer than following joint ; 
anterior margin of mesonotum with pair of small oval, gran- 



ulose areas; wings without tuft of setae at juncture of alar lobe 
and upper squama ; setal arrangement and venation as in Core- 
thra. Male clasp without claw ; sidepiece with or without lobe. 
Genotype, Tipula crystallina De Geer. 

The larvae are aquatic, predaceous, without breathing tube, 
but rest horizontal at various depths in the water, nicely 
balanced by the pair of air-bladders in each end (Howard, 
Dyar & Knab, Mosq. No. & Cent. Am. & W. I., i, Plate viii, 
facing p. 168, figs. 1 and 2, 1912). I'he air-tubes of the pupae 
are closed, but filled with air, serving to hold the pupae vertical 
in the water.

Chaoboms (Chaoborus) eluthera, new species. 

Male and female: Very similar to crystallina, with same 
type of thoracic coloration, dark mesonotal disk with contrast- 
ing yellow lateral margin. The abdomen of the male is much 
more elongate and slender, the tergites appearing twice as long 
as broad (but little longer than broad in crystallina). The 
female is of a uniform paler color. Male with clasper more 
slender and rounded apically ; eighth tergite, surface view, with 
well developed triangle shape, apex caudad; tenth sternites, 
basal three-fourths with distinct angle and parallel side, apical 
fourth suddenly constricted and tapering to a point.

Chaoborus albipes Felt, N. Y. State Museum Bull. 79, 363, 1904. 

The adult of this species differs from crystallina chiefly by 
its lighter, pale orange color and more delicate appearance. 
The tenth sternites of the male taper to a sharp point, being 
claw-like in appearance. 

C. albipes may eventually prove to be the European species, 
flavicans Meigen. It is very similar in coloration and ap- 
parently bears the same relation with crystallina in this country 
as flavicans bears to crystallina in Europe. As we do not 
possess European males of flavicans, and the hypopygium of 


iNsecuTo* iNscm^e mbnstruus 

the male has not been described, we are unable to determine 
this point at present.
